Answer to Question #174980 in Organic Chemistry for Brianne

Question

2ClO₃^- + N₂+ 2H₂ON₂H₄ + 2ClO₄^-

In the above redox reaction, use oxidation numbers to identify the element oxidized, the element reduced, the oxidizing agent and the reducing agent.

Answer 1

2ClO₃^- + N₂+ 2H₂O = N₂H₄ + 2ClO₄^-

The actual way of the reaction is from the right to left:

N₂H₄ + 2ClO₄^- = 2ClO₃^- + N₂+ 2H₂O

In this reaction N₂H₄ (N^-2) is reducing agent, ClO₄^- (Cl⁺⁷) is oxidizing agent. Cl⁺⁷ is reduced to Cl⁺⁵, N⁺² is oxidized to N⁰
