Electroplating Part 2

Here's well look at more details of electroplating. We'll talk about oxidation and reduction, anodes and cathodes. We'll write half reactions for the two processes that are happening in the electroplating cell. How does electroplating work? It is a process where you usually take an object made of one type of metal, and cover it with a thin layer of another type of metal. Usually, precious metals like gold, silver, or platinum are the metals that are electroplated. In an electroplating cell, electrons are removed from one of the metals, which is an oxidation process that happens at the anode. This causes the metal to develop a charge turn into an ion, and allows it to dissolve in the solution. Then, at the cathode, reduction takes place, and the metal ion turns into a neutral atom, and sticks to the surface of the other metal.

i have never seen someone who is happy while explaining sonething as u do, u are a great person thx for the videos they are really helpful and easy to understand thanks to u

[lyleseptember]

Its how a teacher takes so many lessons to explain this and then you come and make a few videos about elctrochemistry and I understand everything.Thanks you really helped me a lot.

[dimathabeynayake]

you should win the Nobel prize for teaching, you are truly the best

[fedrafajardo]

After getting taught by you, I'm actually smiling, because I finally get it. I have online school and we have to learn things twice as fast, that's a hassle, these videos are a blessing.

I love how you smile as you explain the process. It shows your dedication and passion for science. I didn't really understand this process at all and who knew it only took me 30 minutes to fully get it! It's all thanks to you!

i've never understood chemistry this much in my life. Thanks a lot it' actually really helpful.

[lavlavland]

your enthusiasm is what makes these videos so interesting and easy to understand, love it

[sandeepghosh]

Thank you sir, you make it really fun. I wish our school teachers were like you.

Hi, Tyler Dewitt. I'm from Peru.
I just want to thank you for your amazing classes.

[shafagh_projects]

I am so sad that how much time I have lost at my school with the terrible teachers and awful education system. in return your lovely descriptions of chemistry changed my life. thank you so much.

[jeongjiah]

Well, returned back home after giving my chemistry exam..
And guess what?
I ROCKED MY EXAM!
ALL CREDITS GO TO YOU
THANK YOU SO MUCH
You are the bestest teacher and an amazing person!
Thank you so

[trish_s]

You are so passionate about what you teach us and that's what makes learning special... and showing that you truly enjoy it made me enjoy and understand it completely too! Thank you so much!!

I am in the industry of producing rectifiers used for electroplating. I am fresh out of tech school, and had never learned electroplating/ high power rectifiers. Your videos have saved me hours of trying to learn it by myself. Thank you Tyler

[mamoonaawan]

i have seriously no words after looking at your hardwork .YOUR VIDEOS OR LECTURES ARE LIKE MORE THAN WOW .

[klunett]

You are an absolute LIFE SAVER. My chemistry teacher doesny explain anything. I just learned a whole topic worth in three videos. Thank you so much you beautiful soul .

[balabarconchristinemae]

All of your videos shows enthusiasm whenever you talked about chemistry, and that what makes me inspired to learn more about my course. Even though my prof recommended some videos for more explanation about the certain topic, however, I do not really watched them- just few, it is because i learned more and i enjoy them when you were the one who's explaining.

[nnennadoris]

All I have to say is God bless you, you are a one in a million, a live saver

[deej_ed]

I just can't put into words how thankful I am. He literally saved me from crying over that horrifying textbook.
