WebIn the Brønsted–Lowry definition of acids and bases, a conjugate acid–base pair consists of two substances that differ only by the presence of a proton (H⁺). A conjugate acid is formed when a proton is added to a base, and a conjugate base is formed when a proton is removed from an acid. Created by Yuki Jung.

WebThe Brnsted Definition of Acids and Bases. The Brnsted, or Brnsted-Lowry, model is based on a simple assumption: Acids donate H + ions to another ion or molecule, which acts as a base. The dissociation of water, for example, involves the transfer of an H + ion from one water molecule to another to form H 3 O + and OH-ions. WebpKa - The pKa value is the negative base -10 logarithm of the acid dissociation constant (Ka) of a solution.
