Indicate whether each statement is true or false:
(a) If you compare the solubility of a gas in water at two different temperatures, you find the gas is more soluble at the lower temperature.
(b) The solubility of most ionic solids in water decreases as the temperature of the solution increases.
(c) The solubility of most gases in water decreases as the temperature increases because water is breaking its hydrogen bonding to the gas molecules as the temperature is raised.
(d) Some ionic solids become less soluble in water as the temperature is raised.
