    Hello, just a small question, how are you suppose to know what state symbol a chemical has for example (g), (l), (s), or (aq) or your not suppose to know at GCSE Level?

    Thanks

    Well, I certainly didn't use it in my GCSE exam.

    You know because you should know acids are always (aq) and alkalis (I think) and you should just.... know what stuff is solid, liquid or gas. I do... :-o

    Most things you come across in GCSE will be pretty obvious as to what state they will be in. Water is always one to watch as you need to remember that some reactions use steam H2O(g) and that a lot of people put H2O(aq) instead of H2O(l).

    I think I am right in saying it will say 'including state symbols' as well, if they want them.

    Even upto A2 they dont seem to care much about state symbols. Sometimes states they are necesarry though but more often than not they don't want em. Except on born haber cycles though.
