Question

1. if you spill a little of the unknown as you mix it with the water, will the reported freezing point be too high or too low? why? (1pts) (4pts) extension

Explanation:

The freezing - point depression is a colligative property. When a solute is added to a solvent (water in this case), the freezing point of the solution is lower than that of the pure solvent. If a little of the unknown is spilled, there is less solute in the water. With less solute, the magnitude of freezing - point depression is smaller. So the reported freezing point will be too high compared to the correct value for the intended concentration of the solution.

Answer:

The reported freezing point will be too high because there is less solute present in the water due to the spill, resulting in a smaller freezing - point depression.
