12-2 Conjugate Acid/Base Pairs (Section 16.1) To illustrate the idea of “conjugates”, let’s look at the reaction of hydrochloric acid with water and the Brønsted-Lowry definition of acids as H+ donors and bases as H+ acceptors: HCl + H2O → Cl- + H3O+ acid base conjugate conjuga...
proton from an acid to a base. In an acid-base reaction, one bond is broken, and another one is formed. The electron pair of the base B: forms a new bond to the proton of the acid. The acid H—A loses a proton, leaving the electron pair in the H—A bond on A. Acids and ...

base - a compound that dissolves in water to increase the number of hydroxide ions, OH –, in solution. Strong bases are ionic compounds that contain a metal ion and a hydroxide ion, for example, NaOH, sodium hydroxide. Weak bases, such as ammonia, NH 3, ionize incompletely in water to...
