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

0.00246

B

0.0246

C

0.246

D

2.46

Text Solution

Verified by Experts

The correct Answer is:
A
`"For every 1 mole of "Ca^(+2)" ion 2 moles of "C_(8)H_(7)SO_(3)Na" is used."`
`"Uptake of "Ca^(+2)" ion by resin in mole/g"=(1)/(2xx206)=(1)/(412)=0.00246`
