PYQ NEET- Electrochemistry L-4

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: increase in ionic mobility of ions#

Sol:#

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