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?

A

`(1)/(103)`

B

`(1)/(206)`

C

`(1)/(309)`

D

`(1)/(412`

Text Solution

Verified by Experts

The correct Answer is:
D
`2 C_(8) H_(7) SO_(2)Na + Ca^(2+) to (C_(8) H_(7) SO_(3))_(2) Ca + 2Na`
