Question

The molar conductivity of a strong electrolyte at infinite dilution is 240 S cm² mol⁻¹. If its molar conductivity at 0.01 M is 228 S cm² mol⁻¹, what is the degree of dissociation at this concentration?

Options

Choose one · Correct answer highlighted

0.95 Correct 1.00 0.90 0.85

Explanation

For a strong electrolyte, α = (Lambdam/Lambdam°) , but here it’s less than 1 due to ion interaction. α = (228/240) = 0.95 .
