oxidation and reduction agents

Postby Belle Calforda3f » Wed Mar 14, 2018 12:16 am

How do we know which part of the anode is the reduction agent and which part of the cathode is the oxidizing agent?

For the cathode, the oxidizing agent is the reactant that gains the electrons. For the anode, the reducing agent is going to be on the left hand side of the reaction, opposite the side that gains the electrons. So for example, in test question 6, H+ gains the electrons so it is the oxidizing agent. Ni loses the electrons in the anode reaction so it is the reducing agent.
