    Same, but some people said the question is '"which ions" so they put the H+ ions in the HCLO caused the colour change. Not entirely sure which one is right though.
    Ions was not part of the question there. It asked us about the Ions at the last bit of the question

    For the Amount of molecules question did people do mass/ MR to get mmoles and times the moles by Avogrados Constant to get number of molecules?
    YES!!!!!!!:cheers:

    But the molecule would be asymmetrical so would it be dipole dipole?

    I wrote that the litmus paper turned blue because an alkali was formed (or something like that). I don't know what the answer is but that's what I wrote. What did you write?

    I worte that it turned red to show that it was acidic, but I don't think that was specific enough to get the marks
