Identify the oxidized substance, the reduced substance, the oxidizing agent, and the reducing agent.
00:11
So there's a principle for oxidation and reduction.
00:17
If the material is oxidized, let's say it's being oxidized, that's equal to say that this material is a reducing agent.
00:35
And what will happen to this substance? generally, it will actually lose electrons.
00:50
And for being reduced, that's equivalent to the oxidizing agent.
01:19
And in such case, we actually gain electrons.
01:29
So now we can look at this reaction, that is copper react with silver nitrate in the aqueous state.
01:43
It produces two more silver solids and copper nitrate.
01:53
So looking at the copper, initially it's a zero valence state.
01:58
And then after the reaction, it becomes copper nitrate...
