Outline the process of softening hard water (10 marks)
1 Answer
Arun
"If, therefore, a hard water containing a dissolved calcium or magnesium salt is passed through a layer of sodium zeolite, the calcium is abstracted and the corresponding sodium salt passes into solution. ..When water is very hard it is sometimes partially softened by a preliminary treatment with lime and soda.
