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.
