Product Details

Electrolysis of water is a popular chemistry demonstration. It is also becoming a popular hands-on lab for students. Microscale electrolysis of water is safe from electric shock since only a 9-volt battery is used. The students will decompose water into 2 parts hydrogen and 1 part oxygen gas by running a small electric current through the water. The hydrogen and oxygen gases collected will be tested for flammability. All chemicals and specialized equipment are provided.

Complete for 30 students working in pairs. Alligator clips and 9-V batteries are required and available separately.

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-PS1-2. 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.
