1.	Assertion (A) Calgon is used for removingCA^(2+) and Mg^(2+) ions from hard water. Reason (R ) Calgon forms precipitates with Ca^(2+) and Mg^(2+)
Answer» Both A and R are TRUE and R is the CORRECT EXPLANATION of A Both A and R are true but R is not a correct explanation of A A is true but R is fales Both A and R are fales. Solution :Both assertion (A) and reason ( R) are not true. Correct Assertion : Calgon mask the properties of `Ca^(2+)` and `MG^(2+)` ions present in water without REMOVING them as ppt. Correct Reason. Calgon forms soluble complexes with `Ca^(2+)` and `Mg^(2+)` in which properties of these ions are masked.
