Question
Indicate whether each statement is true or false:(a) If you compare the solubility of a gas in water at two dif-ferent 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 hy-drogen bonding to the gas molecules as the tempera-ture is raised.(d) Some ionic solids become less soluble in water as the temperature is raised.
Explanation / Answer
1. is true. Decrease in temperature leads to increase in solubility of gas in water.
2. False. The solubility of ionic solids in water increases as the temperature increases. As ions move faster leading to more interactions with the solvent.
