Salts and Acid-Base Neutralization Salts In chemistry, the term salt refers to the ionic product produced when any base reacts with any acid. The salt gets its cation from the base and its anion (anything but OH-) from the acid, e.g. HCℓ(aq) + NaOH(aq) → H2O(l) + NaCℓ(aq) (table salt) H2SO4(aq) + 2 LiOH(aq) → 2 H2O(l) + Li2SO4(aq) H3PO4(aq) + 3 NH3(aq) → (NH4)3PO4(aq) salts HCℓ(g) + NH3(g) → NH4Cℓ(s) CH3COOH(aq) + CH3NH2(aq) → CH3COOCH3NH3(aq) Acid/Base Neutralization An acid-base neutralization reaction is the chemical reaction between any acid and any base in which both the starting acid and starting base are entirely consumed. That is, all the protons that can be removed from the acid have been removed; all of the proton removal capacity of the base has been satisfied. The most commonly encountered neutralization reactions occur in liquid solution and involve hydroxide bases, hence the definition in the text, page 262. However, NH3(aq) + HCl(aq) NH4Cl(aq) is an acid/base neutralization reaction, despite the text book’s definition.
