        (ii) Volumetric analysis
        Titration is used to determine, accurately, the volumes of solution required to reach the end-point of a chemical reaction. An indicator is normally used to show when the end-point is reached. Titre volumes within 0.2 cm³ are considered concordant.

        Neutralisation reactions
        A neutralisation reaction is one in which a base reacts with an acid to form water. A salt is also formed in this reaction.
        In an acid-base titration, the concentration of the acid or base is determined by accurately measuring the volumes used in the neutralisation reaction. An indicator can be added to show the end-point of the reaction
