Cover a Nail with Copper
I wanted to see metal rust. This experiment didn’t cause rust, but it did make metal change color. Mom says we can do an rust experiment later.
I mixed 1/4 cup white, distilled vinegar and a pinch of salt in a small jar.
I pulled about 20 pennies out of my bank and put them in the jar.
My book said to us iron nails but all we had was steel. So I scrubbed the steel nails with a scouring pad and put them in too.
My book said that it would take about 15 minutes. But we waited several days.
The copper from the pennies and the vinegar combined to form copper acetate. The copper in the copper acetate covered the nail with copper.
