Question

Assertion: Specific conductivity of all electrolytes decreases on dilution.

Reason: On dilution, the number of ions per unit volume decreases.

Options

• Both Assertion and Reason are true and Reason is the correct explanation for Assertion.

• Both Assertion and Reason are true but Reason is not the correct explanation for Assertion.

• Assertion is true but Reason is false.

• Assertion is false but Reason is true.

Answer 1

Both Assertion and Reason are true but Reason is not the correct explanation for Assertion.

Explanation:

The number of ions in a given volume determines conductivity. Both strong and weak electrolytes conductivity diminishes as concentration falls. The number of ions per unit volume that carry current in a solution falls as it is diluted. As a result, conductivity drops. As a result, both assertion and reason are true, and reason is the appropriate explanation for assertion.
