water is usually purified by the addition of certain electrolytes such as potash alum‚ aluminium sulphate etc. This involves the phenomenon of coagulation. The impure water usually contains dispersed colloidal particles which cannot be removed by filtration. When potash alum is added to impure water‚ the negatively charged colloidal particles of impurities get coagulated by the action of Al3+ ions furnished by the alum and can be removed by filtration or decantation. 3.
