Question

Which element is the reducing agent in this reaction? 2KMnO4+3Na2SO3+H2O→2MnO2+3Na2SO4+2KOH

Answer 1

Hi,
this one is a redox reaction.
which mean here substances have oxidized and reduced at the same time

Answer 2

When redox reactions happens the oxidation number of elements which participate for reaction change

Answer 3

here ,
oxidation no.of Mn and S has changed

Answer 4

which mean one out of (MnO4)-ion or (SO3)2- ion has either oxidised or reduced

Answer 5

Is it appropriate to say that MnO is the reducing agent?

Answer 6

oxidizing no. of Mn in(MnO4)- ion has decreased from +8 to +4
oxidizing no. of S in SO# ion has increase from 4 to 6

Answer 7

so MnO4 has reduced

Answer 8

Which mean reducing agent is the (SO3)- ion

Answer 9

hope this will help ya!
