Vedclass · Answer

(D) The conductance of a saturated solution depends on both the ionic mobility and the solubility of the salt. For $NaCl$,which is highly soluble,the solubility does not change significantly with temperature,but ionic mobility increases with $T$,so $C_{NaCl}$ increases. For $BaSO_4$,although ionic mobility increases with $T$,the solubility of $BaSO_4$ is very low and its dissolution is endothermic. However,the increase in ionic mobility generally dominates the conductance behavior in dilute solutions. Wait,re-evaluating: The solubility of $BaSO_4$ increases with temperature. Therefore,both the number of ions and the ionic mobility increase with $T$. Actually,the statement that $C_{BaSO_4}$ decreases is false because both factors (solubility and mobility) increase with temperature for $BaSO_4$.

Let $C_{NaCl}$ and $C_{BaSO_4}$ be the conductances (in $S$) measured for saturated aqueous solutions of $NaCl$ and $BaSO_4,$ respectively,at a temperature $T.$ Which of the following is false?
