sodium sulfate — acid–base reaction Sodium sulfate, also called Glauber's salt, is, like other salts, the product of an acid-base reaction.

The conjugate base of acetic acid (CH₃CO₂H) is the acetate ion (CH₃CO₂⁻).1

According to the Brønsted–Lowry definition, an acid is a species that tends to lose a proton (H⁺), while its conjugate base is the species that remains after the proton has been donated. In the case of acetic acid, the loss of a proton results in the formation of the acetate ion, forming a conjugate acid–base pair.12
