        Strong and weak acids and bases
        In aqueous solution, strong acids/bases are completely dissociated into ions but weak acids/bases are only partially dissociated
        The acid dissociation constant is represented by Ka or by pKa where pKa = –log₁₀Ka

        (b) differences in behaviour between strong and weak acids and bases in terms of the acid dissociation constant, Ka
        (d) how to use pH, Kw, Ka and pKa in calculations involving strong and weak acids and pH and Kw in calculations involving strong bases
        (e) shapes of the titration curves for strong acid/strong base, strong acid/weak base, weak acid/strong base and weak acid/weak base systems
