Question

Purifying water with aluminium sulphate (alum).
Plz explains it in detail ​

Answer 1

Answer:

Aluminium sulfate is used in water purification and as a mordant in dyeing and printing textiles. In water purification, it causes suspended impurities to coagulate into larger particles and then settle to the bottom of the container (or be filtered out) more easily. This process is called coagulation or flocculation.
