Solubility and Temperature—Student Laboratory Kit

By: The Flinn Staff

Item #: AP6636

Price: $23.35

The Solubility and Temperature Chemistry Laboratory Kit is the perfect lab for students to learn about solubility. In many cases, “rules” do not apply to solubility patterns, so the solubility can only be found through a solubility curve.

Product Details

The solubility of compounds in water can vary widely with temperature. In many cases, “rules” do not apply to solubility patterns, so the solubility of a chemical can only be determined through experimentation and construction of a solubility curve. In this lab activity, students will create the solubility curve for potassium nitrate—a compound with a solubility in water that increases 1700% from 0 to 100 ºC! Students will measure saturation temperatures for six different concentrations of potassium nitrate, and then make a solubility curve from the data. Graphical analysis of the data allows students to determine at a glance whether a solution is unsaturated, saturated or supersaturated. Includes reproducible student handouts, detailed background information, Teacher Notes with sample data and answers to questions and all necessary chemicals and consumable supplies.

Complete for 30 students working in pairs.
