        (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.

        pH
        The pH scale is an indication of the hydrogen ion concentration and runs from below 0 to above 14.
        Acidic solutions have a higher concentration of H⁺(aq) ions than OH⁻(aq) and have a pH below 7.
        Alkaline solutions have a higher concentration of OH⁻(aq) ions than H⁺(aq) ions and have a pH above 7.
