SUMMARY
In the reaction Na2SO4 + 4 C → Na2S + 4 CO, sodium sulfate (Na2SO4) is reduced. This conclusion is drawn from analyzing the oxidation states of the elements involved. Sodium sulfate's sulfur changes from +6 in Na2SO4 to -2 in Na2S, indicating a reduction. The carbon (C) is oxidized to carbon monoxide (CO), confirming the redox nature of the reaction.
