Oxygen Production The Russian Space Agency uses potassium superoxide $\left(\mathrm{KO}_{2}\right)$ for the chemical oxygen generators in their space suits.
$$4 \mathrm{KO}_{2}+2 \mathrm{H}_{2} \mathrm{O}+4 \mathrm{CO}_{2} \rightarrow 4 \mathrm{KHCO}_{3}+3 \mathrm{O}_{2}$$

Key Concepts

Chemical Oxygen Generators

Devices that produce oxygen through controlled chemical reactions, often used in environments where conventional oxygen supplies are not available. They are essential in applications such as space suits or submarines, where generating breathable oxygen is critical for survival.

Reaction Stoichiometry

The calculation and balancing of the quantities of reactants and products in a chemical reaction. It ensures the conservation of mass and atoms, allowing for the precise determination of the amounts of substances needed to complete a reaction and produce desired outputs, such as oxygen.

Superoxide Chemistry

The study and application of compounds containing the superoxide ion, which is a reactive oxygen species. These compounds, like potassium superoxide, participate in reactions that generate oxygen through interactions with other chemicals, making them valuable in oxygen production systems.

Life Support Systems

Systems designed to maintain a livable environment by providing essential elements such as oxygen, temperature control, and waste removal. Chemical oxygen generators are a key component in life support systems, especially in sealed or extreme environments where regular oxygen supplies cannot be relied upon.
