Question

The following curve is obtained when molar conductivity (Îm) is plotted against the square

Answer 1

(a) A is strong electrolyte and B is a weak electrolyte

(b) Molar conductivity of a strong electrolyte (A) increase with dilution as conic mobility increase.

In a weak electrolyte molar conductivity increases steeply with dilution as degree of dissociation increases and hence number of ions increases
