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

Options

A. `1//2`
B. `1//3`
C. `3`
D. `2`

Answer

C

Explanation

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`
