Basisartige

Basisartige is a German term used to describe substances that exhibit base-like properties in chemical contexts. The term is used to characterize compounds that behave as bases according to common acid-base theories, notably Brønsted–Lowry (bases accept protons) and Lewis (bases donate electron pairs).

As basisartige substances, they typically increase pH in aqueous solution and neutralize acids to form salts and water. This broad concept covers a range of compounds that can act as bases in different environments, from strong inorganic bases to weaker bases in solution or in organic media.

Common examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH), calcium oxide (CaO) which forms calcium hydroxide in water, ammonia (NH3), and organic amines such as methylamine (CH3NH2). Carbonate systems such as sodium carbonate (Na2CO3) and bicarbonate (NaHCO3) also create basic conditions in water. The exact base strength and behavior can depend on solvent, concentration, and temperature.

Usage and nuances: the term emphasizes the base-like character rather than a rigid, formal category. In German literature, basisch is often used for the general notion of basicity, while basisartig highlights qualitative resemblance to a base, especially when discussing families of related substances or context-dependent strength. It should not be treated as a fixed classification separate from established acid-base terminology.
