Help!! chemistry titration courseworkWatch
does anyone have chemistry coursework to do for A2 a titration to find out how much iron (ii) and iron (iii) there is in a solution. im supposed 2 research on it but i can find any thing on the internet. does any one know any good sites?? please help!!
potassium manganate (vii) titration can determine iron (ii) content:
MnO4- + 8H+ + 5Fe2+ --> Mn2+ +4H2O + 5Fe3+
and complexometric titration with EDTA can determine iron (iii) content:
Fe3+ + H4Y --> FeY- + 4H+
(where Y is EDTA4- ion)
(i did this coursework...used books for reference)
Thanks for the help.
Have to find the conc of aqueous chlorine solution.
React solution with reducing agent (Fe(II)) then determine the amount of reducing agent left over by titration.
So is it a titration of fe(III) from
Cl2 + Fe2+ -> 2Cl- + Fe3+
or a titration of fe(II) that would be left over?
