The van't Hoff factory `i` for an infinitely dilute solution of `NaSO_(4)`is :

A

`1//2`

B

`1//3`

C

`3`

D

`2`

Text Solution

Verified by Experts

The correct Answer is:
C
If the solution is infinitely dilute,`NaHSO_(4)`would dissociate completely.
`:.NaHSO_(4)rarrNa^(+)+HSO_(4)^(-)`
`HSO_(4)^(-)`would further dissociate as:
`HSO_(4)^(-)rarrH^(+)+SO_(4)^(-)i=3`
