brønstedbaserad

Brønstedbaserad is a term used in chemistry to describe a base according to the Brønsted-Lowry theory of acids and bases. This theory, proposed by Johannes Brønsted and Thomas Lowry, defines an acid as a substance that can donate a proton (H+), and a base as a substance that can accept a proton. Therefore, a Brønsted base is any substance that can accept a proton from an acid. This can occur through a proton transfer reaction, where the base accepts the proton from the acid, forming a conjugate acid of the base and a conjugate base of the acid. The strength of a Brønsted base is determined by its ability to accept a proton, which is influenced by factors such as the electron density on the base and the stability of the resulting conjugate acid. Examples of Brønsted bases include hydroxide ion (OH-), ammonia (NH3), and water (H2O). The Brønsted-Lowry theory provides a more comprehensive understanding of acid-base behavior compared to the earlier Arrhenius theory, which only considered hydroxide ions in aqueous solutions.
