    So iron (II) compound is in a beaker, and 25cm^3 is added.

    Then I added this solution (2cm depth) to boiling tube.
    I add H2O2(aq) to boiling tube.

    What would observations be?


    Is this right?

    Pale yellow solution forms due to Fe3+(aq) as H2O2 oxidises Fe2+ to Fe3+

    I have another question. You know how it says, iron II) compound, what would that be? Like FeSO4 or something?

    hydrogen peroxide oxidises Fe2+ to Fe3+ in acidic solution. most likely your iron(II) salt would be that of iron(II) halides made up in acid.
    your observation of Fe3+ (i.e. the colour change) depends on how concentrated is your Fe3+ (aq) produced.
