Step 4: Giving An Iron Nail A Copper Coat

Picture of Giving An Iron Nail A Copper Coat
Peering into the glass you should be able to see that the nail has changed colour. On closer inspection you can see that the iron nail now has a partial copper coating.

The lemon juice and white vinegar are weak acids, which is why the wait times are slightly long. If your acidic level is higher you may find that your wait times are reduced. The more oxidised copper you add to the solution, the more copper ions can be suspended in the solution.

Rinse off your nail and copper after use to stop them discolouring. Also don't forget to pour the solution away and clean the glass before reuse.

Cool! Thanks for sharing that! I often wonder why people choose lemon rather than lime, which is both more acidic and more..."active" or...I don't know how to say...more "varied" or, perhaps, more "drivable" or say..."tunably" 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 "intentions". 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 "technical" 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...
