State whether each of the following statements is true or false. Justify your answer in each case. (a) When acetone, $\mathrm{CH}_{3} \mathrm{COCH}_{3}$, is dissolved in water, a conducting solution results. (b) When ammonium nitrate, $\mathrm{NH}_{4} \mathrm{NO}_{3}$, dissolves in water, the solution is weakly conducting and basic in nature.
