Introduction to Acid-Base Properties of Salt Solutions
A salt is an ionic compound that is produced when a cation and an anion from an acid-base
reaction combine. In other words, the cation from a base replaces a proton on an acid.
An example is the reaction of the strong base NaOH with the strong acid HCI. In solution,
the H¹ and OH ions react to form H₂O, leaving a solution of salt ions. Na+ and Cl
In this example, the salt ions do not affect the pH of the solution and are, therefore, said to
be spectator ions. The conjugate base of a strong acid is always a weak base (and the
conjugate acid of a strong base is always a weak acid). So the conjugate base C1 of the
strong acid HCl is always a weak base and the conjugate acid Nat of a strong base
NaOH is always a weak acid.
However, anions from weak acids and cations from weak bases change the pH of an
aqueous solution. If one of the salt ions is the conjugate acid of a weak base, the ion will
react with H₂O to create H3O+ ions, acidifying the solution. Similarly, the conjugate base
of a weak acid will react with H₂O to create OH ions, making the solution more alkaline.
It can also happen that both of the ions in the salt can react with H₂O. In this case, the pH
of the solution can be more difficult to predict, and it depends on the extent to which each
of the ions hydrolyzes (reacts with water).
