Question

Balance the following redox equation and identify the element oxidized, the element reduced, the oxidizing agent, and the reducing agent. Show all of the work used to solve the problem. 

Br- + MnO2  Br2 + Mn2+

btaylor · Answer

$$2Br^- + MnO_2 \rightarrow Br_2 +Mn + O_2$$
Oxidized: Br, because it loses electrons
Reduced: Mn and O, because they gains electrons
Oxidizing Agent: Mn and O, because they are reduced
Reducing Agent: Br, because it is oxidized.
