Q.13 Which of the following solutions of KCl has lowest

Answer 2

Heyy there,
Your question is rather incomplete.

● Complete question is -
The solution of KCl which has the lowest value of equivalent conductance is
(a) 1 M
(2) 0.1 M
(3) 0.01 M
(4) 0.001 M

● Answer -
(a) 1 M

● Explaination-
Equivalent conductance of the solution is given by -
λ = 1000k/C
λ ∝ 1/C

Therefore, the KCl solution with highest molality i.e. 1 M will have lowest value of equivalent conductance.

Hope this helps...
