2.Yes becoz freezing point is directly propotiomal to the solubility .If u add salt to it it stay solid as a long.

3.Alka Seltzer tablets easily dissolve in hot water than the cold. Water releases hydrogen ions that can react with the base inside the Alka Seltzer tablet, sodium bicarbonate .

. The lower the temperature, the slower the molecules move—and the less it is that the bicarbonate will contact hydrogen present in water.
