Colligative properties are those that depend on the number of particles dissolved in a solvent. The more particles in the solvent, the greater the effect the solute has on the properties of the solution. Examples of colligative properties include boiling point elevation, freezing point depression, vapor pressure depression, and osmotic pressure. Which aqueous solution has the lowest vapor pressure?
