Question

ALUM IS USED TO CLEAN WATER IN WATER TANKS THIS CALLED LOADING HOW DOES THE CHEMICAL HELP WHAT HAPPENS IF WE DO NOT USE IT

Answer 1

Alum, also known as aluminium sulfate is added to water in order to destabilize the mud particles suspended in it. This process is known as coagulation.

Alum helps in purifying water by aluminium which coagulates the mud particles. Because of the high charge on the aluminium ion (Al

+3

), it helps the small particles of suspended solids to group together until they are of such size that they sink and can be removd.
