Question

How does an active cathode take part in a chemical reaction?

Answer 1

Batteries have three parts, an anode (-), a cathode (+), and the electrolyte. The cathode and anode (the positive and negative sides at either end of a traditional battery) are hooked up to an electrical circuit. The chemical reactions in the battery causes a build up of electrons at the anode.

Answer 2

Explanation:

reduction

If a chemical species loses one or more electrons, this is called oxidation. The opposite process, the gain of electrons, is called reduction. Oxidation occurs at the Anode. Reduction occurs at the Cathode.
