I already know the rules in finding the oxidation number I just don't know how to get it in this one.
Australopithecus
  • Australopithecus
Sulfate has a charge of -2
Australopithecus
  • Australopithecus
Thus we can conclude that Magnesium would have a charge of +2

I would assume

It is from KMnO4 + KCl + H2SO4 = K2SO4 + MnSO4+Cl2+H2O I already determined the other oxidation number from this except for MnSO4

How about for oxygen? isn't it it should have an oxidation number of -2 ?

MnSO4 +H2O ----> Mn^(2+) + SO4^(2-)
Australopithecus
  • Australopithecus
Oxygen, -2, -2, -2, -2 Sulpher is a less electronegative element so it will give up its electrons more readily S has +6 6 -2 -2 -2 - 2 = -2 charge total
Australopithecus
  • Australopithecus
I could be wrong, as I'm going off what I have read on Wikipedia and my knowledge of chemistry
Australopithecus
  • Australopithecus
I'm basing this on the fact in Oxygen Diflouride OF2 Oxygen has a charge of +2 instead of -2 because fluoride is more electronegative than oxygen

and since PO4 is a polyatomic anion, I would expect it to maintain its integrity while bonded to manganese, although this is speculation on my part I hope it is helpful.

If you have any questions feel free to ask

So the oxidation numbers will be Mn(+2)S(+6)O4(-2) I based in your statement "Sulfate has a charge of -2 Thus we can conclude that Magnesium would have a charge of +2"
moongazer
  • moongazer
Is it correct?
Australopithecus
  • Australopithecus
O4 should probably have a charge of -8 if S has a charge of +6
Australopithecus
  • Australopithecus
but your conclusion seems correct other wise, Remember Oxygen can attract and hold electrons better than sulfer, so sulfer basically becomes an electron source for the oxygen so they can be more like Neon, making Sulfer more like Neon as well instead of what it usually wants to be like Argon
Australopithecus
  • Australopithecus
I'm pretty sure the -2 charge is just distributed through out all the oxygen atoms until manganese comes along and donates 2 of its electrons
Australopithecus
  • Australopithecus
wait you are probably correct if it is asking for the charge of each individual atom separately :)
moongazer
  • moongazer
I am getting all the oxidation numbers separately for balancing. Thanks :)
Australopithecus
  • Australopithecus
To be honest with you I have never had to answer a question like this I dont think
Australopithecus
  • Australopithecus
But I have taken a lot of chemistry courses in my life so I dont know that has to count for something
moongazer
  • moongazer
Did you mean you haven't balanced a reaction using the oxidation state change method ?
moongazer
  • moongazer
anyway, thanks for the help :)
Australopithecus
  • Australopithecus
yeah
Australopithecus
  • Australopithecus
I had some other method when I did these problems that I cannot remember, but yeah no problem thanks for the question chemistry problems subside the insanity for me :)
