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

Dilution of strong electrolytes increases ionisation , hence ionic mobility of ions which in turn increases equivalent conductance of the solution .
