káliumkarbonáttal

Káliumkarbonát, also known as potassium carbonate, is an inorganic compound with the chemical formula K₂CO₃. It is a white, crystalline salt that is highly soluble in water, forming a strongly alkaline solution. In its natural state, it can be found in the ashes of burnt wood and plants, which is how it got its common name, "potash." Historically, it was extracted from this source, hence the name.

The compound is produced industrially through several methods, including the electrolysis of potassium chloride or the reaction of potassium hydroxide with carbon dioxide. It is a key ingredient in various manufacturing processes. For instance, it is used in the production of glass, particularly specialty glass, and in the formulation of soaps and detergents, where its alkalinity helps in cleaning. It also finds application in the food industry as a food additive, often used as a drying agent or to regulate acidity.

In agriculture, potassium carbonate can be used as a fertilizer to supply potassium to plants, though it is less common than other potassium-based fertilizers. It also plays a role in the production of certain fireworks and in some historical pharmaceutical preparations. Due to its hygroscopic nature, it readily absorbs moisture from the air, making it important to store it in airtight containers. The compound is generally considered safe when handled properly, but its alkaline nature requires caution to avoid skin and eye irritation.
