potas

Potas is a term that appears in various languages as a reference to potassium, the chemical element with symbol K and atomic number 19. In some contexts, potas is used as a local or shorthand form for potassium or for potash, the potassium-containing compounds derived from natural minerals or wood ash.

Potassium itself is a soft, highly reactive metal when in its elemental form and is stored under oil or in an inert atmosphere to prevent oxidation. In everyday practice, discussions about potas typically center on its compounds rather than the pure metal. Potash traditionally refers to potassium carbonate or potassium chloride, substances widely used in agriculture as fertilizers and in industry for chemical processes.

In biology, potassium is essential for cellular function, nerve impulse transmission, and muscle contraction. It helps regulate fluid balance, acid-base balance, and blood pressure. The majority of dietary potassium comes from fruits, vegetables, and dairy products, and recommended intakes vary by age and health status. Deficiencies are uncommon in developed regions but can occur with poor nutrition or certain medical conditions; excessive potassium intake or certain kidney problems can lead to hyperkalemia, a potentially dangerous condition.

Industrial and agricultural applications of potas- or potassium-containing compounds include fertilizer production, food processing, and the manufacture of chemical reagents. Potassium compounds are also studied in the context of energy storage research, including exploratory potassium-based battery technologies.
