Question

The ionization constant of a weak electrolyte (HA) is 25 × 10^–6 while the equivalent conductance of its 0.01 M solution is 19.6 S cm² eq^–1. The equivalent conductance of the electrolyte at infinite dilution (in S cm² eq^–1 ) will be

(A) 250 

(B) 196

(C) 392 

(D) 384

Answer 1

Correct Answer is: (C) 392 

Ka = 25×10^–6 ∧_eq = 19.6 Scm² eq^–1 , C = 0.01 Ka = 0.01 × α₂
