Product Details

Light up your students’ interest with this eye-catching demonstration! Explore precipitation, conductivity and acid–base chemistry, all in one fun demo! At first, the clear pink solution lights up the light bulb on the conductivity tester. As sulfuric acid is added, the light gradually fades and the solution turns milky white. If you continue to add acid, the light begins to brighten again! All solutions come ready made for easy use. A great kit to improve student understanding of these complex topics.

Note: A conductivity sensor with a bulb is required and available separately.
Concepts: Acid and bases, conductivity, precipitation.
Time Required: 20 minutes.

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.
