Question

A conductivity cell with two electrodes (dark side) are half filled with infinitely dilute aqueous solution of a weak electrolyte. If volume is doubled by adding more water at constant temperature, the molar conductivity of the cell will:

Canvas Classes · Accepted Answer

Strategy:
 Analyze the behavior of conductivity in the limit of infinite dilution for weak electrolytes.

Conceptual Analysis:
1. Infinite Dilution: By definition, at infinite dilution, the \degree of dissociation () has already reached its maximum value ().
2. Conductivity () vs. Molar Conductivity (): Further adding water decreases the number of ions per unit volume, making  approach zero. 
3. Molar Conductivity:  is a constant for a given pair of ions. Doubling the volume from an already "inf
