Solubility and Temperature—Student Laboratory Kit

By: The Flinn Staff

Item #: AP6636 

Price: $28.19

In Stock.

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.

Performance Expectations

MS-PS1-1: Develop models to describe the atomic composition of simple molecules and extended structures.
MS-PS1-2: Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
HS-PS1-1: Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
HS-PS1-2: Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-3: Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.
