AIPMT MAINS 2010 Chemistry Conductance MCQ Question

Type: MCQ-conceptual-Medium-Class 12

Which of the following expressions correctly represents the equivalent conductance at infinite dilution of Al₂(SO₄)₃? Given that Λ₀Al³⁺ and Λ₀SO₄²⁻ are the equivalent conductances at infinite dilution of the respective ions?

A

2Λ₀Al³⁺ + 3Λ₀SO₄²⁻

B

Λ₀Al³⁺ + Λ₀SO₄²⁻

C

(Λ₀Al³⁺ + Λ₀SO₄²⁻) × 6

D

1/3 Λ₀Al³⁺ + 1/2 Λ₀SO₄²⁻

Correct Answer

Option B

Detailed Explanation

The equivalent conductance at infinite dilution is the sum of the conductances of the ions, so Λ₀ = 2Λ₀Al³⁺ + 3Λ₀SO₄²⁻.
