    What did people put for the colours and reactions question of bromine water iodine solution,
    For bromine water and Iodine solution:

    Br2 + 2I- -> I2 +2Br-

    at the cyclohexane layer, the solution would become orange.

    could someone link/make an unofficial mark scheme please? also does anyone have any predictions for grade boundaries, considering past paper boundaries and how easy/difficult this paper was in comparison to previous ones. thanks

    Do you know for sure if 'bent' will get the mark also?
    Bent is always in the 'Allow' section of the mark schemes!

    Im so anxious in finding out the grade boundaries, do they want a range of results a-e? if so I'm sure nearly everyone has got above 48... does that mean like 48 would be like an E lol

    The average grade will be a C. Also, I feel like with this type of paper, it's easy to make silly mistakes (I know I did) so I doubt everyone has gotten above 48. Just hope OCR takes pity on us and an A in 46
