Question

An increase in equivalent conductance of a strong electrolyte with dilution is mainly due to:

• A. Increase in ionic mobility of ions
• B. $100\%$ ionisation of electrolyte at normal dilution
• C. Increase in both i.e., number of ions and ionic mobility of ions
• D. Increase in number of ions

Answer 1

The correct option is A Increase in ionic mobility of ions

Strong electrolytes are completely ionised at all concentrations. On increasing dilution, the no. of ions remains the same but the ionic mobility increases and the equivalent conductance increases.
