Study Notes

Potassium Superoxide (KO2)

Utilized in space capsules, submarines, and breathing masks due to its ability to generate oxygen.
Effective at removing carbon dioxide (CO2) and carbon monoxide (CO), maintaining breathable environments.

Potassium Cyanide (KCN)

Commonly used in the extraction process of precious metals like silver and gold.
Serves as a germicide in agricultural applications.
Notably more toxic than sodium cyanide, posing significant health risks.

Potassium Hydroxide (KOH)

Known as caustic potash, primarily employed in the production of soft soap.
Its aqueous solution, referred to as potash lye, is important in various chemical applications.

Potassium Carbonate (K2CO3)

Plays a key role in agriculture and chemical manufacturing, particularly as a fertilizer.
Important for the production of potassium sulfate and involved in the glass-making industry.

Potassium Sulphate (K2SO4)

Commonly known as potash or pearl ash, used as a fertilizer, especially effective for crops like tobacco and wheat.
Essential in the manufacturing of potash alum, contributing to various industrial processes.
