NANSLO Remote Lab Activity: Colligative Properties -- Freezing Point Depression

This NANSLO lab activity is self-contained and can be used in general chemistry and survey of chemistry courses. In this activity, the effects of dissolved materials on the freezing point of the solvent are explored. The lab activity includes background information on colligative properties and how to calculate the relationship between freezing point and the amount of dissolved solute using equations provided, and practical applications of freezing point depression. The lab activity includes information on estimating error, pre-lab questions, a lab exercise, and post-lab analysis activities.
Primary Material Type:

Quality Note:
Curriculum expert in this discipline worked with Discipline Panel of faculty to define learning objectives needed for this lab activity. During development, teleconferences were held to discuss lab activity being developed. Draft activity was posted to listserv for review by Discipline Panel and other faculty in that discipline. Based on feedback, lab activity was modified prior to posting as final. Experts in remote web-based science labs who are also science faculty worked together to define the web-enabled interface design used by students to perform the lab activity via the Internet and created the lab setup (robotics, scientific equipment, and items needed to complete the lab activity) testing it with lab technicians and others prior to launching the final lab activity.
