The acid-base titration is an analytical method to determine the concentration of an acid or base in aqueous solutions by neutralizing the acid/base in solution by a basic/acidic reagent. The endpoint of the solution depends on the relative strengths of the used acids and bases. A neutral solution will be obtained only if a strong acid reacts with a strong base, any other combination will shift the endpoint either towards the acidic direction (lower pH values) or more basic solutions (pH values above 7.0). Thus the endpoint of a titration must be indicated by a proper acid-base indicator whose color changes at the pH value of interest.
