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 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.
Ifboth 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
The conductivity of electrolyte is very low as compared to metal at room temperature because of the very small number of free electrons as compared to a metal. Conductivity is dependent on the free charge carriers as these are only responsible for the current flow. So, the assertion is correct. Furthermore, electrons travel at a much faster speed than ionized particles, because they are way lighter than ions.
