Question

35. When a concentrated solution of a strong electrolyte is progressively diluted, which of the following perfectly describes the trends in its specific conductance ($\kappa$) and molar conductivity ($\Lambda_m$)?

Prashant Kotian · Accepted Answer

Correct answer: B. Specific conductance () decreases upon dilution because the number of current-carrying ions per unit volume () strictly decreases. Molar conductivity () increases because the total volume holding 1 mole of electrolyte increases much faster than decreases, and interionic friction drops.
