Q. Which one of the following graphs between molar conductivity $(A_m)$ versus $\sqrt{C}$ is correct?

JEE MainJEE Main 2019Electrochemistry

Solution:

Both NaCl and KCl are strong electrolytes and as $Na^{+} (aq.)$ has less conductance than $K^{+}(aq.)$ due to more hydration therefore the graph of option (2) is correct.
