If a salt is made from a weak acid and strong base, then the acid anion would get partially protonated by water, like $\ce{CH3COO- + H2O <=> CH3COOH + OH-}$, and that $\ce{OH-}$ would be responsible for the overall alkaline pH of the resulting solution. Please register to post comments. However, now we understand that these equivalences are expressed in terms of moles. First of all you need to know that a buffer normally comprises of a strong base and a weak acid or vice-versa. In Chapter 4 “Chemical Reactions and Equations”, Section 4.1 “The Chemical Equation”, we stated that a chemical equation is simply a recipe for a chemical reaction.As such, chemical equations also give us equivalences—equivalences between the reactants and the products. asked Jan 30 '16 at 21:50. kane9530 kane9530.
