STANDARD Chemistry Molar Conductivity MCQ Question
What will be the molar conductivity of Al³⁺ ions at infinite dilution if molar conductivity of Al₂(SO₄)₃ is 858 S cm² mol⁻¹ and ionic conductance of SO₄²⁻ is 160 S cm² mol⁻¹ at infinite dilution?
189 S cm² mol⁻¹
698 S cm² mol⁻¹
1018 S cm² mol⁻¹
429 S cm² mol⁻¹
Correct Answer
Detailed Explanation
Using the equation Λₘ(Al₂(SO₄)₃) = 2Λₘ(Al³⁺) + 3Λₘ(SO₄²⁻), we can solve for Λₘ(Al³⁺). Substituting the given values, we find Λₘ(Al³⁺) = 189 S cm² mol⁻¹.
