    Hey guys can anyone tell me all the group 7 reactions we need to know? thank you in advance
    The displacement reactions for Chlorine,Bromine and Iodine.

    Solid Sodium Halides(F,Cl,Br,I) with Sulfuric Acid, and the subsequent redox reactions of HBr and HI.

    Also, the Silver Nitrate test.

    In addtion to these, we also need to know:

    The reaction of chlorine with water to form chloride ions and chlorate (I) ions

    The reaction of chlorine with water to form chloride ions and oxygen

    and,

    The reaction of chlorine with cold, dilute, aqueous NaOH and uses of the solution formed

    Can you tell me the reactions of HBr and HI because the products in my textbook are different from those my teacher taught me, so I'm unsure which is correct

    Just worked that out😊

    Physical:
    Atomic structure
    Amount of substance
    Bonding
    Energetics
    Chemical equilibria, Le Chatelier's principle and Kc
    Oxidation, Reduction and Redox equations

    Inorganic:
    Periodicity
    Group 2 Alkali Metals
    Group 7 Halogens

    Relevant Pratical skills - can some one give specific example of this?

    HBr + H2SO4 = Br2+H2O+SO2
    HI + H2SO4 = I2+H2O+H2S


    For the HI it could make just S instead of H2S too, you need to balance those though
