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

Options

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

A

Explanation

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 conduction increases.
