Bronstedbaserad

Bronstedbaserad refers to a classification of chemical compounds or theories that are based on the Brønsted-Lowry acid-base theory. This theory, proposed independently by Johannes Nicolaus Brønsted and Thomas Martin Lowry in 1923, defines an acid as a proton (H+) donor and a base as a proton acceptor.

In a Brønsted-Lowry acid-base reaction, a proton is transferred from an acid to a base. For example, when hydrochloric acid (HCl) reacts with water (H2O), HCl acts as the acid by donating a proton, and H2O acts as the base by accepting the proton, forming hydronium ions (H3O+) and chloride ions (Cl-). This concept is fundamental to understanding many chemical reactions, particularly in aqueous solutions.

The term "brønstedbaserad" can therefore be used to describe substances that exhibit these proton-donating or proton-accepting properties, or theories that rely on this particular definition of acids and bases. It contrasts with other acid-base theories, such as the Arrhenius theory, which defines acids as substances that increase the concentration of H+ ions in water and bases as substances that increase the concentration of OH- ions in water. The Brønsted-Lowry theory is broader and can be applied to non-aqueous solutions and reactions where proton transfer is the key mechanism, even if hydroxide ions are not involved.
