Question

Quizplus · Accepted Answer

Foreign ions introduced to water lower the freezing point of water due to the colligative property of freezing point depression. This means that the presence of solute particles (foreign ions, in this case) interferes with the formation of the solid phase, thus requiring a lower temperature to freeze the solution compared to pure water.
