Question

For each of the following redox reactions in the, identify the oxidizing agent and the reducing agent.

2Na(aq)+2H2O(l)→2NaOH(aq)+H2(g)
C(s)+O2(g)→CO2(g)
2MnO−4(aq)+5SO2(g)+2H2O(l)→2Mn2+(aq)+5SO2−4(aq)+4H+(aq)

Answer 1

In the first redox reaction, 2Na is oxidized and H2O is reduced. The oxidizing agent is 2Na and the reducing agent is H2O. In the second redox reaction, C is oxidized and O2 is reduced. The oxidizing agent is C and the reducing agent is O2. In the third redox reaction, MnO4 is reduced and SO2 is oxidized. The oxidizing agent is MnO4 and the reducing agent is SO2.

Step-by-step explanation:

In the first redox reaction, 2Na is oxidized to 2Na+ and H2O is reduced to H2. The oxidizing agent is 2Na and the reducing agent is H2O.

In the second redox reaction, C is oxidized to CO2 and O2 is reduced to O2-. The oxidizing agent is C and the reducing agent is O2.

In the third redox reaction, MnO4 is reduced to Mn2+ and SO2 is oxidized to SO42-. The oxidizing agent is MnO4 and the reducing agent is SO2.
