Question

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.
