    Add aqeuous silver nitrate

    For chlorine, the precipitate should be white
    For Bromine, the precipitate should be cream
    For iodine, the precipitate should be yellow

    Add dilute ammonia to check if the precipitate only contains those specific ions. If it does, the precipitate will disappear/go clear

    The questions are worded different in each exam but relatively have the same answers. If you're still not confident with Chemistry just memorize a couple of answers it should help answer "some" of the questions in the exam

    Silver Nitrate!

    CHLORINE:
    - White precipitation formation; dissolves in dilute Ammonia.
    BROMINE:
    - Cream "; dissolves in concentrated Ammonia.
    IODINE:
    - Yellow "; insoluble.

    They're almost all the same! That's probably the reason for high boundaries.

    plus the exam is only out of 60, for unit 2 the grade boundaries are much lower since that exam is out of 100. I don't see why one exam is out of 60 and the other is out of 100 for both AS and A2.
