Question

Which of the following salts of same concentration will have same value of van't Hoff factor as that of K₄[Fe(CN)₆]?

विकल्प

• MgSO₄

• Na₂SO₄

• Al₂(SO₄)₃

• Al(NO₃)₃

Answer 1

Al₂(SO₄)₃

Explanation:

The salts which dissociate to give same number of ions and concentrations have same van't Hoff factor for K₄[Fe(CN)₆] = 5

1. MgSO₄ = 2 ions

2. Na₂SO₄ = 3 ions

3. Al₂(SO₄)₃ = 5 ions

4. Al(NO₃)₃ = 4 ions
