Experiment 13: Colligative Properties

The following freezing temperatures will be recorded in this lab: A. The pure solvent, stearic acid B. The pure solvent, water C. The solution of stearic acid with water D. The pure solvent, unknown acid E. The solution of stearic acid with an unknown fatty acid F. The solution of unknown fatty acid with water

A and E

Colligative Property Definition

A property or characteristic that changes from adding solute to a solvent

What is the main purpose of Experiment 13? A. Experimentally determine what the definition of molality is B. To identify an unknown acid dissolved in stearic acid through the colligative property of freezing point depression C. Define what a colligative property is D. Navigate through the procedure and collect data

B

At different elevations, compounds can have different van't hoff factors.

No, it depends on the identity of the solute.
