Question

An increase in equivalence 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. increase in both i.e., number of ions and ionic mobility of ions
• D. at normal dilution $100$% ionisation of electrolyte

Answer 1

The correct option is B increase in ionic mobility of ions

With dilution of a strong electrolyte, the inter-ionic interactions decrease and ionic mobility increases. This increases the equivalent conductance of the electrolyte.

Hence, option B is correct.
