On the other hand, a conjugate base is what is left over after an acid has donated a proton during a chemical reaction. Although we are taught that conjugate base of an acid is what you get after removing a proton. Through examples found in the sections on acids and bases proton-transfer processes are broken into two hypothetical steps: (1) donation of a proton by an acid, and (2) acceptance of a proton by a base. /Type /Page a) O2 b) O- c) H2O d) O2- e) H3O-.
