- In this science experiment, I'll show you how to make a copper quarter using electroplating and explain the chemical reactions behind this cool science project. The longer you let it run, the thicker the copper layer will be, as detailed in Faraday's Law of Electrolysis.

▶️ How to do copper plating/electroplating:
Step 1: Pour 1 liter of warm water into a 1000 mL beaker. The warmer, the better because more copper sulfate will be able to dissolve into the solution.
Step 2: Add 200-300 grams of copper sulfate.
Step 3: Stir until completely dissolved in solution.
Step 4: With the 9-volt battery, connect a red alligator clip to the positive terminal and a black alligator clip to the negative terminal.
Step 5: Connect the loose end of the red alligator clip to a spare piece of copper, such as the copper wire coil we used here (anode).
Step 6: Connect the loose end of the black alligator clip to a separate piece of copper holding the coin (cathode).
Step 7: Carefully place the anode and cathode in solution and observe.
REMINDER: Be sure to keep them at least 3 centimeters apart so you don't overheat the battery with a short circuit.
▶️ How electroplating science works:
The flow of electrons creates an oxidation-reduction reaction. This causes copper from the anode to enter the solution and copper from the solution to deposit on the quarter. The copper will plate the quarter within 5 to 10 minutes, depending on a few variables such as the temperature of the solution, the concentration of copper sulfate, and the voltage and current coming from the battery.

My teacher from Udvash,Bangladesh sent me this video in the PDF for better understanding.Thanks a bunch BeardedScienceGuy and the teacher of Udvash ,Bangladesh Mr. Sadat Ahmed Dipro vaia
I did this years ago and it was fun. Now I tutor and do Upward Bound in a community college. They will not let me have copper sulfate in the lab. And many other chemicals. The state dept of education (Virginia) has a whole list on their web site of chemicals prohibited in middle and high schools and community colleges. A lot of experiments I did in school cannot be done because the reagents are prohibited.
I made my own copper ion solution by using copper as an anode and a cathode which gave me such a corrosive liquid putting a very heavily Patina copper pipe in for 2 seconds made it pure shiny copper
great videos. Thank You. May you reach 100K soon.
Nice work 🌼
What do you khnow about Red mercury
Tried electroplating copper on to nickel, iron and aluminum. Iron got very less copper deposits on it than nickel and aluminum did not get plated at all. Can you please explain why?
Plate in nickel first than plate in copper, nickel seems to bind to most things way better and copper loves to plate to nickel
Excellent Explaination 👀
May be do that on solution from uraniom .maby obtain uraniom 35 from materil contain U35.?
It was fascinating
Wow very eazy I understand
love!!! SCIENCE !!! n I love the Videos !!! very cool!!! n Creative!!
very impressive
Thanks sir
Awesome!!!! But will it take the eyelash off of your screen?
Smally Bells I actually tried lmao I hate you😂😂 I tried sooo many times XD
Smally Bells The eyelash is too small.
Sir but whay no sining? Please
once done the plated copper layer is getting wiped off.. why?

See this Video, He explained why.
great bro
Nice
what type of metal is being coated on the quarter?
What chemical is the source of the Cu2+ ions in the solution
What is the power source?
Did you not watch the video...?
How bleatching black dolar
nice
V. Good
2/2/2021 Came here to cus my teacher told me to prepare my lessons by watchin it
What does cus mean? I highy recommend you learn english first. That way your able to read dangerous chemical warning signs. Id hate to see you get hurt. You inability to spell correctly does my head in.
@@Jason-gk6ms What does Id and highy mean? I highly recommend you learn English first. That way your able to read dangerous chemical warning signs .
You asked me what does cus mean I would recommend you to search it in urban dictionary and about my spelling it was a typing mistake don't worry about me. think about "𝓱𝓲𝓰𝓱𝔂" and "𝓘𝓓"
Why do i get black deposits on my penny?
Are there some disadvantages using a usual 5V DC smartphone charger? Are those transformers capable for this?
fischly96 how are you going to separate 2 terminals?
0:23/1:27
where can I get copper sulfate?
Rep Tile probably on Google 😉
Will this work with silver or gold?
Yes, but they usually add several steps to ensure a better finish and minimize any material loss.
This is as interesting
Was
have to i change copper piece and copper sulfate after how many time ?
Please tell me
Thanks
You do need to change the copper piece if it gets completely used, but as long as you keep the solution closed from air, it should last for a while.
