To find the pH of a basic solution, the same procedure can used. The following equations must be used.
When a strong acid reacts with a base, a neutral salt and water are the products. The reverse reaction is an example of a hydrolysis reaction. A hydrolysis reaction is a reaction of water with a compound that changes the pH of water to a value other than 7.
The reaction of an acid with a base is a neutralization reaction. When the acid and base are both strong, the resulting solution will have a pH of 7. When a strong acid reacts with a weak base, the resulting solution will be slightly acidic. When a strong base reacts with a weak acid, the resulting solution will be basic. When a weak acid reacts with a weak base, the resulting pH of the solution will depend on the strength of the weak acid versus the weak base. The conjugate acid of a weak base is a strong acid and the conjugate base of a strong acid is a weak base.
