    If your learning everything in one day coz you literally know nothing, it would be impossible for me
    I'm learning bits of the spec that I wasn't bothered to memorise at the beginning

    any one got quick method to remember those stupid colours
    i was in ur shoes earlier today this was the best i came across

    https://chemrevise.files.wordpress.c...ion-metals.pdf

    last two page have all the colours youll need to know. unfortunately theres no shortcut, u just have to make up a pattern that works for you or just cram it raw.

    one thing ive noticed tho is the colours tend to repeat for the same metal e.g. fe2+ is mostly green for everything and copper is pretty much blue for everything

    Fe2+ is mostly green for everything, Fe3+ is yellow with water and forms a brown ppt with everything else

    True, some exams are so mentally exhausting that by the end my hand is so tired and my brain feels like mush so writing a 3 instead of a 2 is entirely possible 😂

    I don't know what exam board you do for bio (I do OCR) but gene technology is in the middle of our syllabus so imagine having to do all the gene tech and then having to do ecology and plant and animal behaviour after it....

    I think it's because both the reactant and product on that side are solid so the platinum electrode is just there to conduct between the two solids

    You know when they ask why this cell is not rechargeable or ammeter reading would fall to zero. I don't understand that.
    Not rechargeable: reactions cannot be reversed

    Ammeter: reactants are being used up

    You don't need every colour spec specifically states fe cu and co in ppt reactions and cu nh3 deep blue cucl4 and cocl4
    Maybe so, but every single colour change has come up before.

    Thanks, I just realised that the metal oxides can't conduct electricity
