In any graph of molar conductivity vs √ C , a weak electrolyte gives a curved decreasing graph strong electrolytes give straight-line decreasing graphs, in which the graph of stronger electrolyte will always be above the graph of the comparatively weaker electrolyte. In option [B], Graph III is curved and corresponds to NH 4 OH which is a weak electrolyte. Graph II I respectively represent NaCl and HCl. (∵ HCl is a stronger electrolyte among the two).

Q. A graph of molar conductivity of three electrolytes $(N a Cl, H Cl$ and $N H_{4} O H)$ is plotted against $C$
Which of the following options is correct ?

$(1) - (N a Cl), (2)_{(} H Cl), (3) - (N H_{4} O H)$

$(1) - (N H_{4} O H), (2)_{(} N a Cl), (3) - (H Cl)$

$(1) - (H Cl), (2), (N a Cl), (3) - (N H_{4} O H)$

$(1) - (N H_{4} O H), (2)_{(} H Cl), (3) - (N a Cl)$
