Question

A saturated aqueous solution, is heated to a higher temperature. With increase in temperature, the solubility increases, but no additional solute is added to the solution. This condition is called as :

• A. dilution
• B. concentration
• C. unsaturation
• D. saturation
• E. supersaturation

Answer 1

The correct option is C unsaturation

A saturated aqueous solution, is heated to a higher temperature. With increase in temperature, the solubility increases, but no additional solute is added to the solution. This condition is called as unsaturation.
The amount of dissolved solute is lower than the maximum possible amount that can be dissolved. This is because the solubility is increased. Thus we can dissolve some extra solute in this solution. The solution in which the amount of solute is less than the maximum amount is called unsaturated solution.
