Anode/ Cathode

Postby Sara Richmond 2K » Mon Feb 24, 2020 9:22 pm

When is a reducing agent an anode or cathode? I thought the general rule was that oxidation= anode and reduction=cathode but If you look at the screen shot this problem uses the reverse. I am confused.

Oxidation occurs at the anode but the thing that is oxidized is called a reducing agent. In contrast, reduction occurs at the cathode but the substance reduced is called an oxidizing agent.

Notice that they use the word oxidizing "agent" and reducing "agent." You are correct in your statement. The oxidizing agent is actually being reduced and the reducing agent is actually being oxidized. So the oxidizing agent is the one taking the electron from the one being oxidized.

The word "agent' is what it refers to as doing the respective action so keep an eye out for that.
