Question

An increase in equivalent conductance of a strong electrolyte with dilution is mainly due to (A) increase in number of ions (B) increase in ionic mobility of ions (C) 100% ionisation of electrolyte at normal dilution (D) increase in both i.e., number of ions and ionic mobility of ions

Tardigrade Admin · Accepted Answer

A strong electrolyte is completely jonised at all concentrations. Hence, number of ions remains same. However, on dilution, interionic forces decrease and hence ionic mobility increases. Therefore, equivalent conductance increases.

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

increase in number of ions

increase in ionic mobility of ions

100% ionisation of electrolyte at normal dilution

increase in both i.e., number of ions and ionic mobility of ions

A strong electrolyte is completely jonised at all concentrations. Hence, number of ions remains same. However, on dilution, interionic forces decrease and hence ionic mobility increases. Therefore, equivalent conductance increases.
