Question about balancing a reaction
« on: July 21, 2020, 01:28:25 PM »
hi, I was asked to balance this reaction :
H3PO4 + KMnO4 + H2SO4 → H3PO4 + MnSO4 + K2SO4+ H2O

can I get some help?
thank you

No reductant. Use H3PO3 or H3PO2 on the left side.

but why there will be no reductant? is this a reversible reaction?

For the redox reaction to happen you need something that gets reduced and something that gets oxidized. There is nothing that can be oxidized in this mixture, all compound contain elements in their highest oxidation state.

Also note you have the same H3PO4 on both sides. This is most likely a mistake, perhaps just a typo.
