So what is electric plating? this is actually a really interesting technique that's used all the time industrially to make things like jewelry and silverware that we see and encounter all the time in our daily lives.
00:17
So it basically is a electrolytic cell in the sense that you have a power source where your anode is hooked up to the positive part because electrons oxidation still happen.
00:31
Of the anode, right? so you're giving up electrons.
00:33
Electrons will flow to the positive, and then electrons will flow from the negative to your, let's say, a bracelet.
00:41
And so let's just say, for example, your cell is made of silver, your anode is made of silver.
00:48
Then what will happen is you will start to develop silver atoms on the outside of your bracelet, pretty much until the entire thing is at least coated in silver.
01:05
So the process of electroplating is coating one metal with another metal, usually a more resistant to oxidation or corrosion metal like silver, for example.
01:19
So silver can still what we call tarnish, which is when it breaks down in air, but that happens over a much longer period of time than rusting does with iron, for example.
01:29
So in electroplating, the same metal reaction, ideally, is happening at your anode and your cathode.
01:35
So at your anode, silver is being oxidized to silver plus.

The electron that's generated is flowing through the blue wire...
