Question

Mark out the correct statement(s) regarding electrolytic molar conductivity.

• A. It increase as temperature increases
• B. It experiences resistance due to vibration of ion at the mean position
• C. Increase in concentration decreases the electrolytic molar conductivity of both the strong as well as the weak electrolyte
• D. Greater the polarity of solvent, greater is the electrolytic molar conduction

Answer 1

Answer: (A), (C), (D)

The correct options are
A It increase as temperature increases
C Increase in concentration decreases the electrolytic molar conductivity of both the strong as well as the weak electrolyte
D Greater the polarity of solvent, greater is the electrolytic molar conduction

Electrolytic molar conductivity increase as temperature increases and the increase in concentration decreases the electrolytic molar conductivity of both the strong as well as the weak electrolyte.

${\lambda }_M=\frac{1000K}{M}$ and as $T\uparrow M\downarrow {\lambda }_M\uparrow$

Also, as the polarity of the solvent increases, the number of dissociated ions increases. So, molar conductivity also increases.

(Polarity of solvent greater : number of ions $\uparrow {\lambda }_M\uparrow$)
