Answer : Decrease in the vapour pressure of the liquid.
Explanation : When a solute is dissolved in a solvent it decreases the vapour pressure of the solvent. Usually the vapour pressure of the solution after mixing the solute is found to be lower than the vapour pressure of the pure solvent.
It is also dependent on the concentration of the solute.
Answer; A decrease in the vapor pressure of the liquid.
Dissolving a solute such as potassium hydroxide in a solvent such as water results in a decrease in the vapor pressure of the liquid.
Explanation; The vapor pressure of a liquid is the equilibrium of a vapor above its liquid. In other words it is the pressure of the vapor resulting from the evaporation of a liquid above a given sample of the liquid in a closed container. The vapor pressure of a liquid in a closed container depends on the temperature.
