Learn the basics about electroplating.
The anode is positively charged, and the cathode is negatively charged. They are immersed in a solution called an electrolyte.
The electrolyte and the anode are selected based upon the material that you are electroplating with. So if you want to create a copper plate on the cathode, you would use a copper anode and a copper based electrolyte solution.
When the battery is turned on, the positively charged ions in the electrolyte are attracted to the cathode. Here, they gain electrons which is known as reduction.
When the battery is turned on, the negatively charged ions in the electrolyte solution are attracted to the anode. The atoms within the anode, so the copper atoms in copper plating, lose electrons which is known as oxidation. These copper atoms are now positively charged and dissolve into the electrolyte solution. Once in the electrolyte solution, because they are now positively charged they are attracted over to the negative cathode. Hence electroplating the cathode.
The electrons flow from the anode to the cathode.
Half equations occur at each anode, with oxidation at the anode and reduction at the cathode.
Just remember, oxidation is loss of electrons and reduction is gain.

it felt like Hermione Granger was explaining 🌚 thank you tho-
-
Plot twist: This is Hermoine and the people talking in the background are Harry and Ron.
-
Thank youuuu, I have a test tomorrow and had no idea how electroplating worked, this made it simply and easy to understand thank youu!!
-
This was a totally eye opening experience for me.....I had a little understanding about Electroplating but I can teach in school now!!...lol
-
Getting a job in Cr plating. Great review of chemistry.
-
good video i understand electroplating much better now
-
it was a really helpful video and it gives more rigidity to understand this lesson more clearly, thank you
-
Thank you so much. This really helped me understand electroplating and electrolysis with active electrodes much better. I was unsure of it in school, but this video has really clarified my understanding. Great job!
-
If they’d shown me this in lesson, I would have understood it, great video 😂😂
-
Very well shown and explained. Brilliant, thank you.
-
Thank you so muchh!! This lesson helped me understand electroplating much easier than all other video lectures i have watched! Keep up the awesome work!
-
This really helped me understand the science behind electroplating more. Thanks a Lot!!
-
THANK YOU SO MUCH!! VERY HELPFUL!! SPECIFICALLY 6 HOURS BEFORE MY CHEM EXAM!!
-
Coppha ions
-
tks for explanation. hope you if in conclusion displayed in writing
-
Best explanation, I salute to your work... Thankyou
-
Excellent demo ... Thank you for posting
-
Thank you but I think there is a little mistake in the conclusion part. The graphics show that Cu2+ ions at the anode lose their charge (not electrons) to become copper. The graphics should show that the anode is copper and then loses two electrons to become Cu2+. Remember that electrons have a negative charge. So in your video, you are showing that when Cu2+ loses two electrons it becomes Cu. This is wrong as it would mathematically give Cu4+ (having lost two negative charges). Therefore the correct way would be to show the copper (zero charges) losing two negative charges (electrons) to become positively charged (Cu2+). So basically, you have it the wrong way around. Otherwise the video was very helpful and clear!

Can i use iron and h2so4 reasion result as solution for plating iron coting on Copper ? Or can i use Ferric chloride solution ( which is used for Pcb etching ) to electro plate iron on Cu ?
-
i have to explain abt this for work stuff and i immediately understood!! i studied chem in uni but i graduated two years ago so ive forgotten stuffs like this!! its nice to get an easy to understand video! thank you
