please help on redox reaction???

[Tonychet2]

fertiliser containing iron II is added to 1M h2so4 and then titrated with potassium manganate,

write the oxidation and reduction reaction???

[Tonychet2]

is oxidation

fe2+ -> fe3+ + e-

reduction

MnO4- + 8H+ + 5e- -> Mn2+ + 4H2O? ??


overall

Mno4- + 8H+ + 5Fe2+ -> Mn2+ + 4H2O + 5Fe3+??? am i rite?

That's correct - balance oxygen by adding water, then balance hydrogens by adding hydrogen ions, then combine the two half-equations into one equation, cancelling out the electrons.

true

write the oxidation and reduction reaction???

true dat.

fertiliser containing iron II is added to 1M h2so4 and then titrated with potassium manganate,

write the oxidation and reduction reaction???

also with this question you will need to (well at least i do) write out a chemical equation between the two to find out which will be the reductant and the oxidant...from there you can just do what the others said!!!!
