Find an answer to your question ✅ "Which element is reduced in this reaction? 2KMnO4+3Na2SO3+H2O→2MnO2+3Na2SO4+2KOH" in Chemistry if you're in doubt about the correctness of the answers or there's no answer, then try to use...2KMnO4 + 3Na2 SO3 + H2 O → 2MnO2 + 3Na2 SO4 + 2KOH Reducing agent in the above reaction shown is : A. K+. B. MnO4−. C. SO32−. D. Answer. Reducing agent in the above reaction shown is SO32− ion as S atom itself is oxidized. The oxidation number of S increases from +4 (in SO32− ) to...2KMnO4 + 5Na2SO3 + 3H2SO4(разб.) = 2KMnO4 + Na2SO3 + 2NaOH = 2Na2MnO4 + K2SO4 + H2O.2 KMnO4 + 3 Na2SO3 + H2O → 2 MnO2 + 3 Na2SO4 + 2 KOH. by stating "S" is the reducing agent, you avoid all that stuff.. but in this case since your instructor stated.. "enter the formula".. I'm guessing he or she is of the "the entire compound not just the S" clan.KMnO4 is an oxidizing agent, Na2SO3 is a reducing agent. Reactants: KMnO4 - Potassium manganate(VII). Search by reactants (KMnO4, Na2SO3, H2O) and by products (MnO2, Na2SO4, KOH).

Answer: KMno4 oxidize. Explanation: it loss proto to reduce oH ion.

you have to depart an area every now and then. Else YA will "..." your textual content as you'll see above

this

2 KMnO4 + 3 Na2SO3 + H2O → 2 MnO2 + 3 Na2SO4 + 2 KOH

no longer this

2KMnO4+3Na2SO3+H2O→2MnO2+3Na2SO4+2KOH

***********

anyway..

.. "reduction".. reasonably literally approach "reduction in oxidation state"

.. "oxidation".. approach the opposite.. "increase in oxidation state"

and

.. "agents" are opposites

taking a look on the balanced equation.

.. all K, O, H and Na remained unchanged in oxidation states.. (you check this!)

and

.. Mn went from +7 in KMnO4 to +4 in MnO4

.. S went form +4 in Na2SO3 to +6 in Na2SO4

since

.. Mn went from +7 to +4.... Mn used to be REDUCED and is the OXIDIZING AGENT

.. S went from +4 to +6.. . ...S used to be OXIDIZED and is the REDUCING AGENT

**********

now..

.. SOME instructors would say "S" is the decreasing agent

.. SOME instructors would say "Na2SO3" is the lowering agent

I might most definitely say "S".. the keep away from the arguments

. (1) Na2SO3 is an ionic forged.. it's actually the SO3(2-) what used to be oxidized

. (2) is it the Na2SO3 or the Na2SO4 that was once "oxidized".. reactant or product

..... .or is it the SO3(-2) or SO4(-2) that is the "reducing agent"?

by pointing out "S" is the lowering agent, you steer clear of all that stuff.. but in this case since your instructor said.. "enter the formula".. I'm guessing he or she is of the "the entire compound not just the S" extended family.

final solution... . Na2SO3
