True or False. The vapor pressure of a solution is directly related to the mole fraction of solute.   true false   True or False. When a solute is added to water, the water in solution has a greater vapor pressure than that of pure ice at 0°C.   true false   True or False. Colligative properties depend on the identity of the solute and on the number of solute particles present.   true false   True or False. When sugar is added to water, the boiling point of the solution increases above 100°C because sugar has a lower boiling point than water.   true false

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
