Introduction to Aluminum Sulfate

Aluminium sulfate is a salt with the formula Al2(SO4)3. It is soluble in water and is mainly used as a coagulating agent (promoting particle collision by neutralizing charge) in the purification of drinking water and wastewater treatment plants, and also in paper manufacturing. Aluminium sulfate is rarely, if ever, encountered as the anhydrous salt. It forms a number of different hydrates, of which the hexadecahydrate Al2(SO4)3·16H2O and octadecahydrate Al2(SO4)3·18H2O are the most common.

Preparation of Aluminum Sulfate

● Aluminium sulphate is formed by reacting with the correct amount of sulphuric acid to freshly precipitated aluminium hydroxide. The solution that results is then evaporated and allowed to crystallize. Accessible as pure, lustrous crystals, granules, or powder.
2 Al(OH)3 + 3 H2SO4 → Al2(SO4)3 + 6 H2O
● Aluminium sulphate is also produced by heating aluminum metal in a sulfuric acid solution.
2 Al + 3 H2SO4 → Al2(SO4)3 + 3 H2↑

Production of Aluminium Sulfatetitle
 

In the Laboratory
Aluminium Sulfate is made by adding aluminium hydroxide i.e., Al(OH)3, to sulfuric acid i.e., H2SO4.
2Al(OH)3+3H2SO4→Al2(SO4)3+6H2O
or it is done by heating aluminium metal in a sulfuric acid solution.
2Al+3H2SO4→Al2(SO4)3+3H2↑

 

From Alum Schists
The alum is a mixture of iron pyrite, aluminium silicate and various bituminous substances. These are found in upper Bavaria, Bohemia, Belgium, and Scotland. These are roasted or exposed to the action of the air. In the roasting process, sulfuric acid is formed. It acts on the clay to form Aluminium Sulfate a similar condition of affairs being produced during weathering action of the air. Later, extracted with water and a solution of Aluminium Sulfate of specific gravity 1.16. This solution is allowed to stand for some time and is then evaporated until iron (II) sulphate crystallizes on cooling. It is then drawn off and evaporated until it attains a specific gravity of 1.40 and decanted from any sediment.

 

From Clays or Bauxite
From clays or bauxite, the material is calcined and then mixed with sulfuric acid and water. Then it is heated gradually to boiling. If concentrated acid is in use then no external heat is required as the formation of Aluminium Sulfate is exothermic. Later, it is allowed to stand for some time and then the clear solution is drawn off.

 

From Cryolite
When cryolite is in use as ore, it is mixed with calcium carbonate and heated and sodium aluminate is formed. Sodium aluminate is then extracted with water and precipitated by sodium bicarbonate or by passing a current of carbon dioxide through the solution. The precipitate is then dissolved in sulfuric acid.

 

Application of Aluminum Sulfate
 
Household Uses

Some of the most common uses of aluminum sulfate are found within the home. The compound is often found in baking soda, although there’s some controversy over whether it’s appropriate to add aluminum to the diet. Some antiperspirants contain aluminum sulfate because of its antibacterial properties, although as of 2005 the FDA does not recognize it as a wetness reducer. Finally, the compound is the astringent ingredient in styptic pencils, which are designed to stop small cuts from bleeding.

Gardening

Other interesting uses of aluminum sulfate around the house are in gardening. Because aluminum sulfate is extremely acidic, it’s sometimes added to very alkaline soils to balance the pH for plants. When the aluminum sulfate comes into contact with water, it forms aluminum hydroxide and a much diluted sulfuric acid solution, which alters the soil acidity. Gardeners who plant hydrangeas apply this property to change the flower color (blue or pink) of the hydrangeas since this plant is very sensitive to soil pH.

Water Treatment

One of the most important uses of aluminum sulfate is in water treatment and purification. When added to water, it causes microscopic impurities to clump together into larger and larger particles. These clumps of impurities will then settle to the bottom of the container or at least get large enough to filter them out of the water. This makes the water safer to drink. On the same principle, aluminum sulfate is also sometimes used in swimming pools to decrease the cloudiness of the water.

Dyeing Fabrics

Another one of the many uses of aluminum sulfate is in dyeing and printing on cloth. When dissolved in a large amount of water that has a neutral or slightly alkaline pH, the compound produces a gooey substance, aluminum hydroxide. The gooey substance helps dyes stick to the cloth fibers by making the dye water insoluble. The role of aluminum sulfate, then, is as a dye “fixer,” which means that it combines with the molecular structure of the dye and the fabric so the dye doesn’t run out when the fabric gets wet.

Paper Making

In the past, aluminum sulfate was used in making paper, although synthetic agents have mostly replaced it. The aluminum sulfate helped to size of the paper. In this process, aluminum sulfate was combined with rosin soap to change the absorbency of the paper. This changes the ink-absorbing properties of the paper. Using aluminum sulfate means that the paper was made under acidic conditions. Use of synthetic sizing agents means that acid-free paper can be produced. Acid-free paper does not break down as fast as paper sized with acid.

 

Aluminum Sulfate General Safety Guidelines

General safety procedures should be followed when handling and storing aluminum sulfate. These include:

All chemical products must be stored and labelled in accordance with the instructions on the safety sheet. Chemicals must normally be stored in their original packaging. If you need smaller amounts of a chemical, the new packaging must be suitable for the substance.

Chemicals must not be stored together with inflammable material and gas cylinders.

Chemical containers must be stored with closed lids when they are not being used.

Equipment for handling and cleaning up spillage must be in readiness and suitable for the stored chemicals. It is suitable to have equipment placed outside the chemical store.

It is important for the fire classification of storage lockers and rooms to match the types and amounts of chemicals stored therein.

Combustible material must be stored in fireproof cupboards or in separate spaces.

Use personal protection equipment (e.g., gloves, face mask) where necessary.

Surplus chemicals and hazardous waste must be dealt with in accordance with the information in the safety data sheet.

First Aid equipment must be available.

Workplaces must be cleaned regularly. There must not be chemical spills on the floor.

Q: Is aluminum sulfate harmful to humans?

A: The substance is severely irritating to the eyes, respiratory tract and gastrointestinal tract. The substance is mildly irritating to the skin. A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. The substance may have effects on the central nervous system.

Q: What does aluminum sulfate do for plants?

A: Aluminum Sulfate helps lower soil pH. 5.0 is a suitable pH for many garden plants that thrive in acidic environments. Aluminum Sulfate helps lower soil pH to this target. We recommend using a soil tester for an accurate soil reading before application.

Q: Is aluminum sulfate bad for soil?

A: Remember that adding aluminum sulfate to soil should be done cautiously and in moderation, as excessive amounts can harm plants and the environment.

Q: What does aluminum sulfate do to water?

A: One of the most important uses of aluminum sulfate is in water treatment and purification. When added to water, it causes microscopic impurities to clump together into larger and larger particles.

Q: Is aluminum sulfate toxic to plants?

A: Aluminum sulfate is safe as long as it is applied exactly as necessary, since aluminum can be toxic to plants when applied in large quantities. For this reason, it is recommended to use elemental sulfur to lower soil pH. Aluminum sulfate acts almost immediately whereas sulfur will take more time.

Q: Why do gardeners add aluminum sulfate to the soil?

A: Aluminium sulphate can also be used as a soil acidifier. The effects are rapid, but large quantities can interfere with phosphorus levels in the soil and may also reduce pH excessively.

Q: What are the natural sources of aluminum sulfate?

A: It has a low pH when combined with water making it capable of burning skin or corroding metal, is water soluble, and able to hold water molecules. When added to alkaline water, it forms aluminum hydroxide, Al (OH)3, as precipitate. It can be found naturally in volcanoes or mining waste dumps.

Q: Is aluminum sulfate safe to touch?

A: The common recognized injury from aluminum sulfate is local tissue irritation. The irritating action is often from hydrolysis to form sulfuric acid and may occur from ingestion, skin or eye contact, or inhalation of dusts and mists.

Q: How long does aluminum sulfate last?

A: For optimum product performance, aluminum sulfate should be consumed within three (3) years of delivery. Storage tanks should be emptied and inspected annually.

Q: What are the properties of aluminium sulfate?

A: It is a white crystalline solid in its anhydrous form and in its solution form it appears as a colourless liquid. Both the forms are non-toxic and non-combustible. Aluminium sulphate is soluble in water but insoluble in ethanol. It is odourless and has a mildly astringent taste, sweet taste.

Q: What type of compound is Aluminium Sulfate?

A: Aluminium Sulfate is an ionic compound. Aluminium Sulfate is a combination of positive and negative ions. Ions are charged atoms, that either be monatomic ions i.e., single atoms or polyatomic i.e., multiple atoms combined to form a charged part. Aluminium forms a + 3 ion i.e., Al+3, and sulphate is the -2 polyatomic ion, (SO4)−2.

Q: How dangerous is Aluminium Sulfate?

A: Aluminium Sulfate is an irritant to the skin and eyes. One should wear gloves and eye protection while dealing with Aluminium Sulfate. Aluminium Sulfate is mildly dangerous if it is swallowed in any way because when the salt is swallowed and can form extremely corrosive sulphuric acid.

Q: What are the properties of aluminium sulfate Al₂(SO₄)₃?

A: The chemical formula of Aluminium Sulfate is Al2(SO4)3. It is a chemical compound typically used as a coagulating agent for purification of drinking water, paper manufacturing, and wastewater treatment plants. It is also known as filter alum or dialuminium trisulfate. It is a white crystalline solid in its anhydrous form. However, in its liquid form, it is colourless. Both these forms are non-combustible and non-toxic. Aluminium Sulfate is water-soluble but insoluble in ethanol. It does not have any odour and has a mildly astringent and sweet taste. When it decomposes it emits highly toxic fumes of Sulphur oxides. Also, the Aluminium Sulfate solution is corrosive to Aluminium. This is produced in the laboratory when Aluminium Hydroxide is added to Sulphuric Acid.

Q: What is the Aluminium Sulfate Formula?

A: Aluminium Sulfate is known to be an ionic compound, which means that it is a combination of both positive and negative ions. An atom or molecule turns into an ion when it loses or gains electrons. Molecules can be either monatomic, which means that they contain one atom, or polyatomic, which means that they contain more than one atom. Most ionic compounds consist of a one metal atom that is a positive ion, and a radical or negative ion that is a negative ion. If you consider Aluminium Sulfate, the positive ion in it is Aluminium ion, Al3+. The radical is the sulfate ion, (SO4)2- that has a negative charge. Since all ionic compounds are electrically neutral, there is a ratio of molecular weight by which the aluminum and sulfate ions react, so their electrical charges are cancelled out. You can determine this ratio by the criss-cross method of deriving a chemical formula.

Q: What are the Applications of Aluminum Sulfate?

A: In Sewage Treatment
Aluminium sulfate is an inorganic salt that is widely used in wastewater treatment as a Coagulant. It makes the impurities’ tiny particles change into a solid or semi-solid state and settle at the bottom. So, purifying the water becomes easy.
In the Manufacture of Paper
Aluminium sulfate is used as a component in the manufacture of paper as it changes the absorbing properties of the paper.
As a Component in Baking Soda
Aluminium sulfate is also found as one of the components of Baking powder.
In the Printing and Dyeing of Fabrics
Aluminium sulfate, when dissolved in alkaline water, results in the formation of a soft and sticky substance. When this sticky substance is mixed with the dyes it sticks to the clothes, making the dye water-insoluble.
For the Remineralization of Drinking Water
Due to Reverse Osmosis water, the minerals present in the water are also eliminated along with the impurities. So, to remineralize the water, small amounts of salt like aluminium sulfate are added to the RO purified water.
As an Enhancing Agent of the Immune System
Along with the disease-causing microorganisms, unrelated chemicals called Adjuvants are also added to the vaccines to enhance the response of the Immune system. Aluminium sulfate is also used as an Adjuvant in some vaccines.
In Construction, Works As a Waterproofing Agent
Aluminium sulfate is a very good Coagulant which makes it used as a Waterproof agent in construction work. It makes the cement mix correctly without any leaks.
As a Fireproofing Agent on Combustible Materials
Aluminium sulfate is a non-combustible material that makes it to use as a Fireproofing agent. Combustible materials are coated with Aluminium sulfate to avoid unnecessary fire accidents.
In Gardening, to Balance the PH of the Soil
The pH of Aluminium sulfate is between 5.5-7.5, which shows that it is a weak acid. So, when the soil is alkaline, to balance the pH of the soil, Aluminium sulfate is used.
As an Astringent, Antiseptic, Anti-Bacterial Agent for Skin-Related Diseases
Astringents help remove the dirt from the skin and balance the skin’s pH. Antiseptics and anti-bacterial agents help to prevent the growth of microorganisms on the skin. So, using Aluminium sulfate, which is an antiseptic, astringent and anti-bacterial, helps to avoid some skin-related issues.

Q: What is the chemical composition of Aluminum Sulfate?

A: Aluminum sulfate exists as white, lustrous crystals, granules, or powder. In nature, it exists as the mineral alunogenite. Aluminium sulfate is sometimes called alum or papermaker’s alum, however, the name “alum” is more commonly and properly used for any double sulfate salt with the generic formula XAl(SO4)2·12H2O, where X is a monovalent cation such as potassium or ammonium (5). Aluminum sulfate has an action similar to that of alum but is more stringent (2). Aluminum sulfate is an aluminum salt composed of aluminum, sulfur, and oxygen, three plentiful elements. Its molecular formula is Al2(SO4)3 or Al2S3O12 or Al2O12S3.

Q: Where is aluminum sulfate used?

A: Water Treatment Applications
Ever wonder how we manage to have safe drinking water flowing out of our faucets? You can thank aluminum sulfate. Municipal water suppliers, such as your local water utility company, make use of alum to treat water for human consumption. In addition, process water (non-drinking water) may also be treated with this chemical for purification when bacteria / sediment would cause an adverse effect. When added to water, aluminum sulfate causes microscopic impurities to clump together into larger and larger particles. These clumps then settle to the bottom of the container and can be filtered out. This makes the water safer to drink. On the same principle, alum is also sometimes used in swimming pools to decrease water cloudiness.
Dyeing Fabrics
Look down at your shirt. It’s likely not a plain white t-shirt. Another of the many uses of aluminum sulfate is in dyeing and printing on cloth. When dissolved in a large amount of water that has a neutral or slightly alkaline pH, the compound produces a gooey substance, aluminum hydroxide. This goo helps dyes stick to the cloth fibers by making the dye water insoluble. The role of aluminum sulfate, then, is as a dye “fixer,” which means that it combines with the molecular structure of the dye and the fabric so the dye doesn’t run out when the fabric gets wet.
Paper Making
In the past, aluminum sulfate was used in making paper, although synthetic agents have mostly replaced it. Aluminum sulfate helps to size the paper. In this process, it is combined with rosin soap to change the absorbency of the paper, which changes the paper’s ink-absorbing properties. Aluminum sulfate produces acidic conditions, whereas synthetic sizing agents produce acid-free paper which does not break down as easily.
Medical Applications
Going to the doctor’s office is never fun, but because of aluminum sulfate usage, the medical field has been able to advance in several ways to keep us healthy. Aluminum sulfate has several practical uses in the medical field. It is primarily used as a coagulating agent in treating minor cuts and abrasions as well as deodorant (due to its antibacterial properties). This compound also adsorbs and precipitates protein antigens in solution; the resulting precipitate improves vaccine immunogenicity by facilitating the slow release of antigen from the vaccine depot formed at the site of inoculation. In addition, solutions containing 5 to 10% have been used as local applications to ulcers and to arrest foul discharges from mucous surfaces. Aluminum sulfate is found in materials used in the pharmaceutical industry. For instance, it is used in the preparation of aluminum acetate ear drops.
