In such a pair A must obviously have one more positive charge (or one less negative charge) than B, but there is no other restriction on the sign or magnitude of the charges. Look it up now! The acid loses a proton to become its conjugate base A- as the base B accepts a proton to become its conjugate acid HB+. NH4+ is the conjugate acid to the base NH3, because NH3 gained a hydrogen ion to form NH4+.The conjugate base of an acid is formed when the acid donates a proton. To join together; specifically, to join in marriage; unite by marriage. A conjugate means a “mate.” If we translate this meaning to acid-base chemistry, then we can say that every acid is tied to its mate called “conjugate base,” and together, they are called a “conjugate acid-base pair.” Chromophores are molecules that can absorb certain wavelengths of light, leading them to be colored. In chemistry, there are three possible definitions of the term "conjugate". Conjugate acid is the tendency of a substance to donate protons or accept electrons during a reaction.
