Urgent: Chemistry A2 Coursework watch

    • Thread Starter

    Hi, I am doing a coursework on the estimation of iron(II) and iron(III) in a mixture containing both. This is a volumetric procedure to determine the percentage of iron 2 and 3. I am provided with 200cm3 of solution containing between 1.1g and 1.3g of iron ions as a mixture and the two ions are present to at least 30% by mass.

    I don't know where to start with this courseowrk? What concentrations and quanities of soultions should I use?
    What method should I use?

    I've been researching for 5 days and have found very little to do with this coursework. I know that manganate has something to do with Iron but how do you link this in? Where do I start from? PLEASE HELP!! THANKS.
