Question

Resistance of a conductivity cell filled with a solution of an electrolyte of concentration 0.1m is 100. The conductivity of this solution is 1.29 sm-1. Resistance of the same cell when filled with 0.2m of the same solution is 520. The molar conductivity of 0.2m solution of the electrolyte will be:

Answer 1

Resistance of a conductivity cell filled with a solution of an electrolyte of concentration 0.1M is 100W. The conductivity of this solution is 1.29Sm–1 . Resistance of the same cell when filled with 0.2M of the same solution is 520W. The molar conductivity of 0.02M solution of the electrolyte will be

(a) 124 × 10–4S m2 mol–1

(b) 1240 × 10–4S m2 mol–1

(c) 1.24 × 10–4S m2 mol–1

(d) 12.4 × 10–4S m2 mol–1 .
