Electric Charges And Fields

Question
CBSEENPH12048034

Assertion:  The conductivity of an electrolyte is very low as compared to a metal at room temperature. 

Reason:  The number density of free ions in electrolyte is much smaller as compared to the number density of free electrons in metals. Further, ions drift much more slowly, being heavier.

  • If both assertion and reason are true and reason is the correct explanation of assertion.

  • If both assertion and reason are true but reason is not the correct explanation of assertion.

  • If assertion is true but reason is false.

  • If both assertion and reason are false.

Solution

A.

If both assertion and reason are true and reason is the correct explanation of assertion.

A current can be carried through an electrolyte is via the movement of ions: which will be slow, and the concentration of ions is low compared to the electrons that are present in bulk metal.
