, K+, and Na+ are 74, 50 and 73 cm2 ohm-1 eq-1, respectively. The equivalent conductance at infinite dilution of the salt
isOptions
A.197 cm2 ohm-1 eq-1
B.172 cm2 ohm-1 eq-1
C.135.5 cm2 ohm-1 eq-1
D.160.5 cm2 ohm-1 eq-1
Solution
Total charge = 2
Number of equivalent of ion =
∴ Eq of
Eq of Na+ =
, Eq of K+ = 
∴ λoeq

= 74 +
= 135.5
Number of equivalent of ion =
∴ Eq of

Eq of Na+ =
∴ λoeq


= 74 +
