Assertion: Calgon is used for removing Ca^(2+) and Mg^(2+) ions from hard water. Reason: Calogon forms precipatate with Ca^(2+) and Mg^(2+) ions.

Assertion: Calgon is used for removing Ca^(2+) and Mg^(2+) ions from h

1.	Assertion: Calgon is used for removing Ca^(2+) and Mg^(2+) ions from hard water. Reason: Calogon forms precipatate with Ca^(2+) and Mg^(2+) ions.
Answer» Solution :(d) Correct assertion: Calgon MAKES `Ca^(2+) and MG^(2+)` ions present in hard WATER ineffective. Correct reason: CALOGON forms soluble complex with `Ca^(2+) and Mg^(2+) ions`.
