Question

Let  and  be the conductances (in S) measured for saturated aqueous solutions of NaCl and  respectively, at a temperature T. Which of the following is false?

Canvas Classes · Accepted Answer

Strategy:
 Saturated solutions are at equilibrium. Conductance depends on both the number of ions (solubility) and the speed of ions (mobility). Both typically increase with temperature.

Evaluation of Statements:
- (a) Ionic mobilities increase with T: Generally true, as viscosity decreases. However, look at the nature of saturation for high vs. low solubility salts.
- (b) and (c): Both statements claim conductance increases with T; this is generally correct due to both solubility and mobility
