`A0.004 M` solution of `Na_(2)SO_(4)` is isotonic with `0.010 M` solution of glucose at same temperature. The apparent percentage dissociation of `Na_(2)SO_(4)` is :

A

`25%`

B

`50%`

C

`75%`

D

`85%`

Text Solution

Verified by Experts

The correct Answer is:
C
`pi_(Na_(2)SO_(4)) = pi_(g10C^(@))`
`ixx 0.004 = 0.010`
`i= 2.5 = 1 +2 prop rArr prop = 0.75 or 75%`
