1.

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

Answer»

`K_(2)SO_(4)`
`K_(3)[Fe(CN)_(6)]`
`Al(NO_(3))_(3)`
`K_(4)[Fe(CN)_(6)]`

SOLUTION :`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.
