Equation for the oxidation reaction for KMnO4 solution

In summary, the conversation involved discussing the half equation for the oxidation reaction and the full net ionic equation for KMnO4 solution mixed with dilute HCL. The main focus was on identifying what was being oxidised, which was determined to be chlorides. Other topics included balancing chemical equations, the oxidation number of sulfur, and the role of certain ions as spectators in reactions. The conversation also touched on various calculators for chemistry-related problems.

2MnO(4-) + 16H(+) + 5SO3(2-) + 50(2-) ---> 5SO4(2-) + Mn(2+) + 4H2O ?

50(2-)

Where did you got it from?

ok so mix diluted hadfield solution (steel dissolved in
nitric acid followed by treatment with ammonium
peroxydisulfate to oxidize carbon and treated with Sn(2+)
to reduce the Fe(3+) to Fe(2+) ) in a conical flask with
some H2SO4 and some KIO4.. the whole idea is to find out
the amount of manganese in the steel.. What is the
oxidation half equation that converts Mn(2+) to MnO4(-)?

I thought Mn(2+) + IO4(-) ---> MnO4- + I- ?

Strange, as far as I know Mn2+ can be oxidized to permanganate by ammonium peroxydisulfate in the presence of catalytic amounts of Ag+; no need for further Fe and oxidation by periodate.

well my notes seem to indicate IO4 has something to do with the oxidation..

It is a strong oxidizer, but I don't see a point in using it here. Perhaps you have not shown complete procedure.
