zasadowa

Zasadowa is the feminine singular form of the Polish adjective zasadowy, used to describe substances or environments that are basic or alkaline in chemistry. The term denotes properties opposite to acidic, and it is commonly applied to describe solutions or materials with a pH above 7. It agrees with feminine nouns, for example substancja zasadowa (alkaline substance) or odczyn zasadowy (alkaline reaction).

In chemistry, a base is a substance that accepts protons or donates electron pairs, and when dissolved in water it typically yields an alkaline solution. Common examples include hydroxides such as wodorotlenek sodu (sodium hydroxide) and wodorotlenek potasu (potassium hydroxide), as well as ammonia in solution. Phrases like roztwór zasadowy or substancja zasadowa are standard Polish descriptions of these bases.

Etymologically, zasadowa is the feminine form of zasadowy, itself a derivative used to indicate basic or alkaline properties. The word is primarily employed in scientific contexts, particularly chemistry and biology, but may also appear in broader discussions of pH, acids and bases. See also kwasowy, kwas, pH, odczyn, which provide related chemical terminology.
