Question

An experiment is designed to investigate the effects of solutes on colligative properties,

Two equal volume sample are placed in a freezer. One is pure water and the other is an aqueous salt (NaCI) solution. What prediction can be made regarding the samples?
• The salt solution will freeze at a lower temperature than the pure water.
• The pure water will freeze at a lower temperature than the salt solution.
• Both samples will freeze at he same temperature.
• Neither of the samples will freeze.

The prediction that can be made regarding the samples is that the salt solution will freeze at a lower temperature than the pure water. This is because adding solutes, such as NaCl, to a solvent (water) decreases the freezing point of the solution compared to the pure solvent. This is known as the colligative property of freezing point depression.
