Product Description

Aluminium Sulphate is an industrial grade chemical compound that is commonly used in industrial and commercial applications. It physically appears as a white or grayish powdered compound which shows excellent solubility in water and has a strong acidic taste. This compound is primarily used as a coagulating agent for the treatment of drinking as well as wastewater to efficiently remove suspended particles, such as dirt, algae, and bacteria. Aluminium Sulphate can also be used for paper production to improve the paper's strength and durability by binding the fibers together. Customers can get this powdered chemical at a low price.

Aluminium Sulphate Properties:

1. Chemical Formula: The chemical formula of aluminum sulfate is Al2(SO4)3, indicating that each molecule contains two aluminum (Al) ions and three sulfate (SO4) ions.

2. Appearance: Aluminum sulfate is typically found as a white or colorless crystalline solid. It can also appear as a fine powder or in granular form.

3. Solubility: Aluminum sulfate is highly soluble in water, which makes it useful for various applications, including water treatment and dyeing processes.

4. Acidic Nature: When dissolved in water, aluminum sulfate releases aluminum ions and sulfate ions. It also has a slightly acidic nature, which can be useful in adjusting the pH of certain solutions.

5. Hygroscopic: Aluminum sulfate has hygroscopic properties, meaning it can absorb and retain water molecules from the surrounding environment.

6. Odor and Taste: Aluminum sulfate is odorless and has a slightly sweet and astringent taste.

7. Density: The density of aluminum sulfate varies depending on the form (solid, powder, or granular), but it generally has a density of around 2.71 g/cm3.

8. Melting and Boiling Points: Aluminum sulfate decomposes before it reaches its melting point. The compound starts to decompose around 770 degreee centigrade without melting, releasing sulfur trioxide gas.

Applications of Aluminium Sulphate:

1. Water Treatment: Aluminium sulfate is commonly used as a coagulant in water treatment processes. It helps in purifying and clarifying water by causing suspended particles and impurities to aggregate and settle, allowing for easier removal.

2. Paper Industry: It is used in the paper manufacturing process to improve paper formation, strength, and sizing. Aluminium sulfate aids in binding the paper fibers and retaining pigments, leading to improved print quality and paper texture.

3. Textile and Dyeing Industry: Aluminium sulfate acts as a mordant in the textile and dyeing industry. It helps fix dyes to fabrics and enhances the colorfastness of the dyes, resulting in vibrant and long-lasting colors.

4. Soil Amendment: In agriculture and gardening, aluminium sulfate is used to adjust soil pH levels. It can lower soil pH and increase soil acidity, making it suitable for plants that thrive in acidic conditions, such as blueberries, azaleas, and rhododendrons.

5. Deodorants and Antiperspirants: Aluminium sulfate is sometimes used as an active ingredient in deodorants and antiperspirants due to its astringent properties. It helps reduce perspiration by temporarily blocking sweat ducts.

6. Fire Retardant: Aluminium sulfate is used as a fire retardant in some applications. When exposed to heat, it releases water vapor, which cools the surrounding area and helps suppress flames.

7. Leather Tanning: In the leather industry, aluminium sulfate is used during the tanning process to help fix and preserve the tanning agents, resulting in improved leather quality and durability.

8. Pharmaceuticals: Aluminium sulfate can be used in pharmaceutical formulations for various purposes, including as astringents in topical treatments and as an ingredient in antacid preparations.

9. Wastewater Treatment: Apart from potable water treatment, aluminium sulfate is also used in industrial wastewater treatment to aid in the removal of pollutants and contaminants.

10. Lake and Pond Treatment: Aluminium sulfate can be used to control algae growth and improve water clarity in lakes and ponds. It helps precipitate algae and other suspended particles, reducing turbidity.

11. Construction and Cement Industry: Aluminium sulfate is sometimes used in the construction industry, primarily as a flocculating agent to improve the setting and hardening properties of cement.

12. pH Adjustment: Aluminium sulfate can be used to adjust the pH of certain solutions, often in laboratory settings or industrial processes where precise pH control is necessary.


Q. What is Aluminum Sulfate?

Ans: Aluminum sulfate, also known as aluminium sulphate, is a chemical compound with the formula Al2(SO4)3. It is a white crystalline solid that is commonly used for various industrial and household applications.

Q. What are the Common Uses of Aluminum Sulfate?

Ans: Aluminum sulfate is used as a coagulant in water treatment, a mordant in the textile industry, a papermaking additive, a soil pH adjuster, and an ingredient in deodorants, among other applications.

Q. How Does Aluminum Sulfate Work in Water Treatment?

Ans: Aluminum sulfate helps purify water by causing suspended particles and impurities to clump together and settle. This aggregation makes it easier to remove these particles from the water during the treatment process.

Q. Is Aluminum Sulfate Safe to Use?

Ans: Aluminum sulfate should be handled with care. While it is generally considered safe for its intended applications, it can be a skin, eye, and respiratory irritant. Proper safety precautions and guidelines should be followed.

Q. Can Aluminum Sulfate Lower Soil pH?

Ans: Yes, aluminum sulfate can be used to lower soil pH and increase soil acidity. It is often used in gardening and agriculture to create acidic conditions suitable for certain plants.

Q. Is Aluminum Sulfate Used in Food?

Ans: Aluminum sulfate is not approved for direct use in food. However, aluminum compounds are sometimes used as food additives in minimal amounts, and aluminum sulfate may indirectly come into contact with food through water treatment processes affecting drinking water.

Q. Can Aluminum Sulfate be Used for Fire Retardation?

Ans: Yes, aluminum sulfate can act as a fire retardant due to its ability to release water vapor when exposed to heat. This cooling effect can help suppress flames.

Q. What is the Role of Aluminum Sulfate in the Paper Industry?

Ans: Aluminum sulfate is used in the paper industry to improve paper formation, strength, and sizing. It helps bind paper fibers together and retains pigments, enhancing print quality.

Q. How Does Aluminum Sulfate Work as a Mordant in Dyeing?

Ans: As a mordant, aluminum sulfate helps fix dyes to fabrics, improving colorfastness. It creates a bridge between the fabric and the dye molecules, allowing for a more permanent bond.

Q. Is Aluminum Sulfate Harmful to the Environment?

Ans: When used improperly or in excessive amounts, aluminum sulfate can have negative effects on the environment, such as altering soil pH and potentially contaminating water sources. Proper usage and disposal are important to minimize environmental impact.

Q. Can Aluminum Sulfate be Used in Cosmetic Products?

Ans: Yes, aluminum sulfate can be used in cosmetic products such as deodorants and antiperspirants due to its astringent properties. However, the use of aluminum compounds in cosmetics is a subject of ongoing research and debate.

Q. Is Aluminum Sulfate the Same as Alum?

Ans: "Alum" typically refers to potassium aluminum sulfate, which is a related compound. While both aluminum sulfate and alum have similar properties and applications, they are not the same chemical compound.
