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 ($\Lambda_m$)?
Answer: B
π‘ Solution & Explanation
Specific conductance ($\kappa$) decreases upon dilution because the number of current-carrying ions per unit volume ($1 cm^3$) strictly decreases. Molar conductivity ($\Lambda_m$) increases because the total volume holding 1 mole of electrolyte increases much faster than $\kappa$ decreases, and interionic friction drops.
