draselné

Draselné is a Czech term used to describe substances that contain potassium (symbol K). In chemistry and related fields, draselné compounds are potassium-containing compounds, and the adjective is often applied to potassium salts, though it can refer more broadly to any material in which potassium is present. The word is derived from draslík, the Czech name for the element potassium, with the suffix -né indicating a property or composition.

Common draselné substances include potassium salts such as potassium chloride (KCl), potassium sulfate (K2SO4), potassium nitrate (KNO3), and potassium carbonate (K2CO3). These compounds are largely ionic and many are soluble in water. In geology and mineralogy, draselné minerály refer to naturally occurring potassium-rich minerals, such as sylvite (KCl) and carnallite (KMgCl3·6H2O), which are important ore sources for potash fertilizers.

Applications: In agriculture, draselné fertilizers supply potassium, an essential macronutrient that supports water regulation, enzyme activation, and overall plant vigor. In industry, potassium compounds serve roles in chemical synthesis, glass production, and as fluxes or electrolytes. In medicine, potassium salts are used therapeutically to correct electrolyte imbalances, under professional supervision.

Safety and environmental notes: Potassium compounds vary in reactivity and solubility; handling and disposal guidelines apply similarly to other inorganic salts. Excessive potassium can be harmful to humans and ecosystems, and regulatory controls govern their use in agriculture and commerce.
