Question

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?

Answer 1

When the aqueous solution is heated to 85âC, the gas entrapped in the aqueous solution is released since the vapour pressure of the particular entrapped gas is more than the solution. The solid saturated in the aqueous solution returns back to its original form once the aqueous solution evaporates. A good example is that of the salt left behind after heating a brine solution to evaporate.
