Featured in PASCO’s College Chemistry Instructor Guide
College Instructor edition with 36 experiments covering introductory and general chemistry topics.
Freezing Point Depression
Use a stainless steel temperature sensor to determine the molecular weight of a compound by measuring the freezing point depression of a solution.
Students determine the molecular weight of a compound by measuring the freezing point depression of a solution.
Students gain experience conducting the following procedures:
- Measuring the freezing point of a solvent.
- Making a solution with a solvent that has a higher freezing point than room temperature.
- Using phase diagrams and obtaining freezing point curves.
Sensors / Equipment Used:
Allows students to measure Temperature, pH/ISE/ORP, Absolute Pressure & Voltage in one sensor. For use with PASPORT Interfaces.
