Which substance is the reducing agent in this reaction?
Express your answer as a chemical formula.?
you have to leave a space now and then. Else YA will “…” your text as you can see above
2 KMnO4 + 3 Na2SO3 + H2O → 2 MnO2 + 3 Na2SO4 + 2 KOH
.. “reduction”.. quite literally means “reduction in oxidation state”
.. “oxidation”.. means the opposite.. “increase in oxidation state”
.. “agents” are opposites
looking at the balanced equation.
.. all K, O, H and Na remained unchanged in oxidation states.. (you verify this!)
.. Mn went from +7 in KMnO4 to +4 in MnO4
.. S went form +4 in Na2SO3 to +6 in Na2SO4
.. Mn went from +7 to +4…. Mn was REDUCED and is the OXIDIZING AGENT
.. S went from +4 to +6.. . …S was OXIDIZED and is the REDUCING AGENT
.. SOME instructors would say “S” is the reducing agent
.. SOME instructors would say “Na2SO3” is the reducing agent
I would probably say “S”.. the avoid the arguments
. (1) Na2SO3 is an ionic solid.. it’s really the SO3(2-) what was oxidized
. (2) is it the Na2SO3 or the Na2SO4 that was “oxidized”.. reactant or product
….. .or is it the SO3(-2) or SO4(-2) that is the “reducing agent”?
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.
final answer… . Na2SO3
