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

Correct option (a) increase in ionic mobility of ions

Explanation :

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