A `0.004 M` solution of `Na_(2)SO_(4)` is isotomic with a `0.01 M` solution of glucose at same temperature. The apparent degree of 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_("Glucose")`
`CRT(1+2 alpha) = CRT`
`0.004(1+2 alpha) = 0.01`
`:. alpha = 0.75 = 75%`
