The molecular formula of a commercial resin used for exchanging ions in water softening is `C_(8)H_(7)SO_(3)Na(mol. wt. 206)` . What would be the maximum uptake of `Ca^(2+)` ions by the resin when expressed in mole per gram resin?

Text Solution

Verified by Experts

`(1 mol Ca^(2+))/((2 "mol resin")(206 g "resin"//mol. "reson"))`
`= 0.00246 mol Ca^(2+)//g "resin"`
