        pH
        The pH scale is an indication of the hydrogen ion concentration and runs from below 0 to above 14.
        Neutralisation reactions
        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

        Indicators
        Indicators are weak acids for which the dissociation can be represented as: HIn(aq) + H₂O(l) ⇌ H₃O⁺(aq) + In⁻(aq)
