basischemische

Basischemische is a term used in German to describe the portion of chemistry that deals with bases and alkaline substances. It is not a standalone scientific discipline, but a facet of general chemistry focused on properties, reactions, and applications of basic (alkaline) species. The concept relies on several definitions of bases, including Arrhenius (a base produces hydroxide ions in water), Brønsted–Lowry (a base accepts a proton), and Lewis (a base donates an electron pair).

Key topics in basischemische include acid–base equilibria, pH and pOH concepts, and neutralization reactions in solution. Buffers—combinations of weak acids and their conjugate bases or weak bases and their conjugate acids—are central to maintaining stable pH in biological, environmental, and industrial systems. The behavior of bases is contrasted with acids in various contexts, from aqueous solutions to non-aqueous media and catalytic processes.

Common bases encountered in practice are hydroxides such as NaOH and KOH, ammonia and amines, carbonates and bicarbonates, and metal oxides like CaO. In biological systems, amine groups and nucleotide bases are important examples of basic sites. Applications span water treatment and soil chemistry (alkalinity and buffering capacity), industrial synthesis (base-catalyzed and base-promoted reactions), paper and soap production, and pharmaceutical formulation.

Safety and handling focus on the caustic and corrosive nature of many bases, appropriate personal protective equipment, and proper disposal. Terminology varies; in many contexts, basische Chemie is encompassed within broader acid–base chemistry and inorganic or organic chemistry, rather than as a distinct, isolated field.
