(For AQA) They will most definitely have you regurgitate how to do a titration (easy), a question on testing for positive/negative ions (hate those), something on environment with either fuels or stuff like that, bond energy calculations (higher), water hardness and possibly ion exchange columns, the history of either the periodic table and/or acids an bases (mendeleev for first and arrhenius, bronsted, lowry), definitely somethibgon periodic table on reactivity and/or transition metals. That's most of it.
