I do have some ideas I've already jotted down but whether or not they will work I have no idea:
Fe^{}2+ - e \rightarrow Fe^{}3+
Using MnO_{}4^{}-+8H^{}+ + 5e \rightarrowMn^{}2++4H_{}2O
Work that out ?
Then (just tell me to stop if this is completely wrong):
Fe^{}3++ e...
Homework Statement
You must devise a volumetric procedure to determine the percentage or Iron(ii) and Iron (iii) in a mixture containing both.
You are provided with 200cm^{}3 of a solution containing between 1.1g and 1.3g of iron ions as a mixture of Fe^{}2+ and Fe^{}3+(aq). You may assume...
