Electrolysis is used to separate substances. Explore the process by building a circuit with simple materials and make sodium hydroxide; one of the most used ingredients in making medicines.
As part of our STEM at home series, we have created some fun, hands-on experiments to engage young people in STEM. They can be completed at home or in school, encouraging students to become lab scientists for the day. As well as including step-by-step instructions and easy to follow diagrams, all can be completed in under 30 minutes with little equipment.
Parental or teacher supervision is advised.
