Temperature Change and Solubility (13.2.1)

Question 1

• In endothermic solvation processes, solubility increases with increasing temperatures, while in exothermic solvation processes solubility decreases with increasing temperature.

Answer 1

• In endothermic solvation processes, solubility increases with increasing temperatures, while in exothermic solvation processes solubility decreases with increasing temperature.

Question 2

• Supersaturated solutions contain more dissolved solute than their solubility at a particular temperature.

Answer 2

• Supersaturated solutions contain more dissolved solute than their solubility at a particular temperature.

Question 3

• Two solutes dissolved in the same solvent can be separated by taking advantage of their different solubilities at different temperatures in a process called fractional crystallization.

Answer 3

• Two solutes dissolved in the same solvent can be separated by taking advantage of their different solubilities at different temperatures in a process called fractional crystallization.
