Which one of the following salts will have the same value of van't hoff factor (i) as that of `K_(4)[Fe(CN)_(6)]`?

A

`Al_(2)(SO_(4))_(3)`

B

NaCl

C

`Na_(2)SO_(4)`

D

`Al(NO_(3))_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
`K_(4)[Fe(CN)_(6)]` dissociates as `4K^(+)+[Fe(CN)_(6)]^(4-)`, thus 1 molecule dissociates into five particles in the similar way `Al_(2)(SO_(4))_(3)` also gives five particles per molecule.
