Concept explainers

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.

Which is true about the freezing point of a solution and the freezing point of a solvent?. Select the correct response: The freezing point of a solution is higher than the freezing point of a solvent. The freezing point of a solution is the same as the freezing point of a solvent. The freezing point of a solution has no relation to the freezing point of a solvent. The freezing point of a solution is lower than the freezing point of a solvent.
