- Two statements, one Assertion and the other Reason are given. Choose the right option.
Assertion: The Molar conductivity of KCl increases very slowly with dilution and approaches a limiting value when dilution is infinite.
Reason: In case of KCl there is an increase in the number of ions on dilution due to complete ionisation at infinite dilution.COMEDK 2026 Medium
