Question
The van′t Hoff factor i for an infinitely dilute solution of NaHSO4 is :
Options
A.1/ 2
B.1/ 3
C.3
D.2
Solution
If the solution is infinitely dilute, NaHSO4 would dissociate completely.
∴ NaHSO4 → Na+ + HSO4-
HSO4- would further dissociate as :
HSO4- → H+ + SO42-
i = 3 ∴ (C).
∴ NaHSO4 → Na+ + HSO4-
HSO4- would further dissociate as :
HSO4- → H+ + SO42-
i = 3 ∴ (C).
