This is a simple experiment you can easily replicate at home using things you may find around the house. It's something people of all skill levels can do and can be a fun little experiment to do with the kids.

Step 1: Materials Needed

List of materials:
  • Oxidised Copper -  copper coins or copper fittings, should be dull indicating it's oxidised
  • Weak Acid Solution - white vinegar or lemon juice is best to see results
  • Salt
  • A Glass container - best for seeing the results
  • Wire wool or other abrasive cleaner.
  • An iron nail - not galvanised - as used in my 'How To Make An Electromagnet' video see that here.
<p>thanks for sharing, copper is one of the most beautiful metals, copper plating is one of my favorite things to do</p>
<p>Cool! Thanks for sharing that! I often wonder why people choose lemon rather than lime, which is both more acidic and more...&quot;active&quot; or...I don't know how to say...more &quot;varied&quot; or, perhaps, more &quot;drivable&quot; or say...&quot;tunably&quot; reactive? I don't know the word I want. Anyway, I'm wondering why did you choose lemon? If you don't mind me asking... Lime is slightly more acidic but like grapefruit, it's also a whole other animal with what is still some pretty mysterious-seeming &quot;intentions&quot;. Nobody ever thinks about the lime and I'm just wondering why that is. Is it merely because people assume it's like a lemon and then dismiss it because it's activities are not the same as a lemon? I've only just begun experimenting with lime juice, but the only &quot;technical&quot; information available seems to be in the field of bartending where it is so obviously NOT a lemon, in its activities with, effects on or reactions TO other cocktail ingredients. And now I'm just rambling...sorry...</p>
Love the puns ?
<p>Its awesome maaaaan........</p>
I like the little cartoon things
Thanks. :)
I have a lot of Ferric acid with copper in it i suppose from etching circuit boards. Would this work with that and a battery?
I'm not trained in chemistry, so I couldn't answer off of the top of my head. But a little search on the internet produced articles saying that dropping iron into the solution copper coated it and re-energised the ferric acid. Also there was mention of using electrolysis, with an iron cathode and a carbon anode. If your unsure how to set-up a home electrolysis kit check out my '<a href="http://www.youtube.com/watch?v=Gl0IPt81-3c" rel="nofollow">Home Electrolysis Kit</a>' video on my Youtube channel. Just do an internet search into it before you try.
Very interesting, you don't use electricity.
Using a power source would yield better results. But this is the simple way and I feel it's easy to replicate whatever skill level you are. <br> <br>Thanks for leaving a comment.
