proton-transfer reaction

A proton-transfer reaction is a fundamental concept in chemistry, often associated with acid-base reactions. In essence, it involves the transfer of a proton (H⁺) from one chemical species to another. While the bare proton (H⁺) is highly reactive and doesn't exist in detectable concentrations in solutions, these reactions are understood through the combination of two processes: one where a species loses a proton and another where a species gains a proton.1234

This transfer can occur in various contexts, including neutralization reactions, where an acid reacts with a base, or the hydrolysis of salts. For example, the neutralization of acetic acid by ammonia can be viewed as a proton transfer from acetic acid to ammonia, resulting in acetate and ammonium ions. Similarly, the dissociation of bases in water involves a water molecule acting as an acid and transferring a proton to the base.142
