Product Details

No one is exempt from an occasional “bout with the blues.” The blues come and go as in this demo. Two colorless solutions and an indicator are mixed, producing a blue solution. Upon standing, the solution becomes colorless. The solution alternates between blue and colorless with shaking and standing, respectively. You’ll wipe those blues away with this fascinating demonstration. Teacher Demonstration Notes included.

Concepts: Oxidation–reduction, indicators, kinetics.
Time Required: 15 minutes

Performance Expectations

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.
MS-PS1-6. Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.
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.
