What is the difference between an anode and a cathode and how does it relate to redox.?

Answer 1

Hmm, let me see if I can remember from my chemistry days...an anode is a negatively charged electrode and a cathode is a positively charged electrode. The are used in redox (which is a shortened version of reduction/oxidation) when the electrodes are dipped into a solution. The reduction (losing of electrons)happens at the cathode and the oxidation (gaining of electrons) happens at the anode. Hope that helps.

Answer 2

Devices to help you remember:

"An Ox" and "Red Cat"
Oxidation occurs at the anode.
Reduction occurs at the cathode.

Can't keep oxidation and reduction straight? Think:
OIL RIG
Oxidation Involves Loss (of electrons).
Reductin Involves Gain (of electrons).

In what direction do the electrons flow?
FAT Cat
From anode to cathode

Answer 3

You are dealing with the electric charges on ions and polar molecules.

Negative charged particles are called anions, and they are attracted to a positive pole. Just the opposite for cations. They are positive charged items and they are attracted to the negative pole.
