Carolina™ AP® Chemistry Each Carolina AP® Chemistry Kit includes comprehensive instruction materials, including exercise objectives, background information, a list of required apparatus, discussion questions and answers, pre-lab and post-lab questions and answers, and suggested lab room preparation. The student worksheet lists the experiment procedure and contains post-lab questions. Addresses lab topics in the Chemistry Examination of the Advanced Placement Program® Includes all chemicals for completing the experiments Provides ample materials for a class of 30 students

Meets AP® Chemistry topic 4. In this powerful illustration of colligative properties, students determine the molar mass of a substance by freezing-point depression.

First, they identify a pure solvent’s freezing point, dissolve their sample in the solvent, and determine the freezing point of this solution.

The freezing-point depression is then used to calculate the sample’s molar mass. All kit materials are reusable and the kit includes a test tube rack for easy storage of freezing-point samples.

An optional procedure for collecting data using temperature probes is included. Materials are sufficient for 30 students working in pairs.
