**Acid-Base Properties of Salt Solutions**

Salt is an ionic compound that is produced when a cation and an anion from an acid-base reaction combine, and solutions of salts can be neutral, acidic, or basic, depending on the acid-base properties of the constituent cations and anions.

Since strong acids and bases completely ionize in solution, the reaction essentially runs to completion forming the salt. Therefore, salts formed by reaction of a strong acid with a strong base are neutral. NaCl formed by the neutralization of NaOH and HCl is a neutral salt.

Salts formed by reaction of a strong acid with a weak base are acidic, and salts formed by reaction of a weak acid with a strong base are basic. This is due to the equilibrium the conjugate has with its acid or base. For example, sodium bicarbonate NaHCO₃ contains the conjugate of the weak acid H₂CO₃. The conjugate will reform the acid through the equilibrium:

\[ \text{HCO}_3^- \ (\text{aq}) + \text{H}_2\text{O} \ (\text{aq}) \leftrightharpoons \text{H}_2\text{CO}_3 \ (\text{aq}) + \text{OH}^- \ (\text{aq}) \]

and, thus, acts as a weak base. A solution of NaHCO₃ yields a basic solution.

If a salt is derived from a weak acid and a weak base, the pH of the solution depends on the relative acid strength (Kₐ) of the cation and base strength (K_b) of the anion. If Kₐ > K_b, the solution of the salt is acidic. If Kₐ < K_b, it is basic. If Kₐ ≈ K_b, it is neutral.
