STANDARD Chemistry Van't Hoff Factor MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Which of the following will have same value of van't Hoff factor as that of K₄[Fe(CN)₆]?
A
Al₂(SO₄)₃
B
AlCl₃
C
Al(NO₃)₃
D
Al(OH)₃
Correct Answer
Option A
Detailed Explanation
K₄[Fe(CN)₆] dissociates into 5 ions (4K⁺ and [Fe(CN)₆]⁴⁻). Al₂(SO₄)₃ also dissociates into 5 ions (2Al³⁺ and 3SO₄²⁻), thus having the same van't Hoff factor.
