Redox, that's short for reduction, oxidation reaction, is a type of reaction that always come in pair.
00:10
Reduction is characterized by the, is characterized again by the gain of electron, whereas oxidation is characterized by the loss of electron.
00:26
One can know whether a species would undergo reduction or oxidation from the reduction potential value that it has.
00:33
So the more positive the reduction potential value is, the more likely that the species would undergo reduction.
00:42
And if it's more negative, it's likely to undergo oxidation.
00:47
So as we can see here, it is the eg plus that has a greater value for the reduction than the i2.
00:55
It follows that it is the first reaction that is the reaction, the cathode, or the reduction half reaction.
01:04
So we say that cathode reaction or the reduction reaction is the first one, since it has a greater or more positive reduction potential.
01:17
So i'm just going to write it here, ag plus aqueous, then plus electrons forming ag solid.
01:27
And the second equation is the oxidation reaction, which occurs at the anode...
