Make-A-Gas Kits: Oxygen

SCIENTIFIC CONCEPTS/PROCESSES

• Preparation and collection of oxygen
• Chemical identification of oxygen
• Study the characteristics of oxygen
• Burn various substances (carbons, metals, non-metals) in oxygen

This Make-A-Gas® generator produces Oxygen when a 6% solution of hydrogen peroxide is reduced by contact with a catalyst of pelletized manganese dioxide. After collecting the gas, students perform several activities to study both the physical and chemical properties of oxygen.

Reactions can be started, stopped and controlled at any point.
