Question

The conductivity of an electrolytic solution decreases on dilution due to ______.

Options

• decrease in number of ions per unit volume

• increase in ionic mobility of ions

• increase in percentage ionisation

• increase in number of ions per unit volume

Answer 1

The conductivity of an electrolytic solution decreases on dilution due to decrease in number of ions per unit volume.

Explanation:

Both the strong and weak electrolytes' conductivity diminishes when their concentration (i.e., dilution) drops. This is owing to the fact that as concentration drops, the number of ions carrying current in a volume of solution reduces as well.
