The Vapour Pressure Of Solutions A solutions vapour pressure is affected by the concentration of solute and the interactions of solute and solvent. salt to melt ice on a footpath-causes the freezing point of the water to decrease thus ice melts if T=0C add a to the water in the radiator of a car to lower the freezing point of the water. The presence of a non-volatile solute lowers the vapour pressure of a solvent.
