NEET Chemistry Conductance of Electrolytic Solutions MCQ Question
A weak monobasic acid is 5% dissociated in 0.01 mol dm⁻³ solution. Limiting molar conductivity of acid at infinite dilution is 4 × 10⁻² Ω⁻¹ m² mol⁻¹. What will be the conductivity of 0.05 mol dm⁻³ solution of the acid?
8.94 × 10⁻⁶ Ω⁻¹ cm² mol⁻¹
8.92 × 10⁻⁶ Ω⁻¹ cm² mol⁻¹
46 × 10⁻⁶ Ω⁻¹ cm² mol⁻¹
23 × 10⁻⁵ Ω⁻¹ cm² mol⁻¹
Correct Answer
Detailed Explanation
Using the formula Λ = Λ₀ × α, where α is the degree of dissociation, we find the conductivity.
