For each described change, determine the generally expected impact on a salt's solubility. LABEL No solubility change, SOLUBILITY DECREASE OR SOLUBILITY INCREASE A- Cooling a saturated solution by 10 oC
B- Placing a saturated solution in a hot water bath
C- Doubling the amount of salt added to a saturated solution

The generally expected impact on a salt's solubility of the given conditions are;

A) SOLUBILITY DECREASE

B) SOLUBILITY INCREASE

C) No solubility change

We are dealing with salts solubility in a aqueous solution.

       Now, the solubility of salt is simply the maximum amount of salt that can be added to a specific mass of water to dissolve it.

       Now, for salt dissolved in an aqueous solution, when the temperature of the solution is increased, the solubility will also increase and when the the temperature of the solution is decreased, the solubility of the solution will also increase.

This definition implies that the higher the temperature, the more the salt that will dissolve and the lower the temperature, the lesser the salt that will dissolve.

Option A; Since the saturated solution is cooled, it means that temperature is reduced and as the solubility would decrease.

Option B; Placing the saturated solution in a hot water bath means the temperature would increase and as a result the solubility will also increase.

Option C; Doubling the amount of salt does not have any effect on solubility as it only increases the saturation of the salt present. Thus, there will be no solubility change.

Solubility increases with increase in temperature and decreases with decrease in temperature.

Solubility refers to the amount of substance that dissolve in a solvent at a given temperature. The solubility of solids is temperature dependent. Hence, the solubility curve is a plot of solubility against temperature. Generally, solubility of solids increases with increasing temperature and decreases with decreasing temperature.

A saturated solution contains just as much solute as it can normally hold at a given temperature. Addition of more solute makes no change in a saturated solution.

Hence, the changes in solubility expected in each case is;

Cooling a saturated solution by 10 oC - SOLUBILITY DECREASE

Placing a saturated solution in a hot water bath - SOLUBILITY INCREASE

Doubling the amount of salt added to a saturated solution - No solubility change
