Which of the following substances cause permanent hardness of water?

Question

Verified by Toppr

Answer 1

Permanent hardness is caused by dissolved chloride, sulfate, and nitrates of Calcium & magnesium (which are not removed by boiling) and temporary hardness is caused by dissolved calcium hydrogen carbonate (which is removed by boiling).

Hence, the correct option is $A$

Answer 2

Permanent hardness is caused by dissolved chloride, sulfate, and nitrates of Calcium & magnesium (which are not removed by boiling) and temporary hardness is caused by dissolved calcium hydrogen carbonate (which is removed by boiling).

Hence, the correct option is

A
