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.
