Aluminium Sulphate Solid

Aluminium sulphate (Al₂(SO₄)₃) is typically a white, crystalline solid or powder. It can also appear as a colourless or slightly yellowish substance, depending on the purity and form.

Common uses of Aluminium Sulphate:

1. • Coagulant in water purification: Aluminium sulphate is commonly used in water treatment plants to remove impurities. It helps in coagulation, where it binds to particles in the water, causing them to clump together and settle at the bottom so they can be removed. This is particularly useful in wastewater treatment.
   • Papermaking: It is used in the paper industry for sizing paper and as a flocculant in the preparation of pulp. It helps to control the paper’s texture, strength, and printability.
   • Mordant in dyeing: In the textile industry, aluminium sulphate is used as a mordant to help fix dyes to fabrics, improving the colour intensity and durability.
   • Acidifying agent in gardening: It is used to lower the pH of alkaline soils in gardens and lawns, making them more acidic, which is beneficial for growing certain types of plants like hydrangeas, blueberries, and azaleas.
   • Pest control: It has applications in pest control, especially in treating plant diseases or as a fungicide in certain gardening and agricultural settings.
