Question

The molar conductivity for electrolytes A and B are plotted against \(C^{1/2}\) as shown below. Electrolytes A and B respectively are :

	A	B
(1)	Weak electrolyte	weak electrolyte
(2)	Strong electrolyte	strong electrolyte
(3)	Weak electrolyte	strong electrolyte
(4)	Strong electrolyte	weak electrolyte

Answer 1

Correct option is (3)

As per the debye huckle ongaser rule

\(\Lambda _ m \alpha A \sqrt {C}\) depends on \(\sqrt {C}\) concentration hence

\(\rightarrow\) \(\Lambda _ m\) of strong electrolyte is linear graph with \(\sqrt {C}\)

\(\rightarrow\) \(\Lambda _ m\) of week electrolyte is non-linear graph with \(\sqrt {C}\)

Hence :

A :- is Weak electrolyte 

B :- is Strong electrolyte
