Question

The conductivity of 0·001 mol L–1 solution of acetic acid is 3·905 × 10–5 S cm–1. Calculate its molar conductivity. If Λ°m for acetic acid is 390·5 S cm2 mol–1, then calculate its degree of dissociation (α).

Solutions of two electrolytes X and Y are diluted. Molar conductivity of X increases 25 times whereas that of Y increases 1·5 times. Which one is a stronger electrolyte ?

Explain the variation of molar conductivity with concentration for strong electrolyte and weak electrolyte with the help of diagram.

Calculate the degree of dissociation (α) of CH₃COOH if Λₘ and Λ°ₘ of CH₃COOH are 48 S cm² mol⁻¹ and 400 S cm² mol⁻¹ respectively.
