- BThe method involves adding a chemical softening agent to precipitate hardness ions from water.
- CThe principle is to boil hard water to remove minerals.
- DThe method involves passing hard water through a filter to physically remove hardness ions.
Correct answer
A. The principle of the method is to exchange the ions (cation and anion both) that form the salts responsible fo
Step-by-step solution
Correct Option is : (A) The principle of the method is to exchange the ions (cation and anion both) that form the salts responsible for hardness in water.
