Which of the following electrolytes has the same value of van't Hoff factor (i)is that of `Al_(2)(SO_(4))_(3)`(if all are `100%`ionised?

A

`K_(2)SO_(4)`

B

`K_(3)[Fe(CN)_(6)]`

C

`Al(NO_(3))_(3)`

D

`K_(4)[Fe(CN)_(6)]`

Text Solution

Verified by Experts

The correct Answer is:
D
`Al_(2)(SO_(4))_(3)` and `K_(4)[Fe(CN)_(6)]` produce the same number of ions in the solution (viz. 5). Hence, they have the same value of van't Hoff factor.
