An aqueous solution is saturated with both a solid and a gas at 5 °C. What is likely to happen if the solution is heated to 85 °C?

View Available Hint (s)

a.) Some gas will bubble out of solution and more solid will dissolve.

b.) Some gas will bubble out of the solution and some solid will precipitate out of the solution.

c.) Some solid will precipitate out of solution.

d.) More gas will dissolve and more of the solid will dissolve.

Answer:

a.) Some gas will bubble out of solution and more solid will dissolve.

Explanation:

Temperature increase usually increases the dissolution of solids in liquids. From the question; Some gas will be bubble out of the solution as the temperature is being increased to 85 °C because that aqueous solution is saturated (i. e equal amount of solute and solvent in the solution) with both solid and gas at 5 °C, but when the solution is heated to 85 °C, the solution becomes supersaturated (i. e the solute is now more at the given temperature than the solvent).

As the temperature increases, the solubility of the solid increases and the solubility of the gas decreases. When the solution that is saturated between a solid and a gas at 5 ° C and heated to 85 ° C, the gas comes out of the solution first.

Explanation:

A saturated solution is one that has the maximum amount of solute that is dissolved. An unsaturated solution is one that has a low amount of solute compared to the saturated solution. According to Henry's law, the solubility of a gas at a specific temperature is directly proportional to its partial pressure, that is

C ∝ p

C = kp

Where

p is the partial pressure

k ia a proportionality constant

C is the concentration of the gas
