Also known as hydronation

In chemistry, protonation (or hydronation) is the adding of a proton (or hydron, or hydrogen cation), usually denoted by H+, to an atom, molecule, or ion, forming a conjugate acid. (The complementary process, when a proton is removed from a Brønsted–Lowry acid, is deprotonation.) Some examples include The protonation of water by sulfuric acid: H2SO4 + H2O H3O+ + The protonation of isobutene in the formation of a carbocation: (CH3)2C=CH2 + HBF4 (CH3)3C+ + The protonation of ammonia in the formation of ammonium chloride from ammonia and hydrogen chloride: NH3(g) + HCl(g) → NH4Cl(s)
