Readers today in Hurumanu 5 Science, we were working on electroplating with copper. You have to put your clips onto the positive and negative terminals of power supplies.
Equipment: Safety glasses, beaker, power supplies, wires with clips, copper sulfate solution.
Discussion: Copper in the blue solution was cu2+(Blue part), with an electrical current turned into Cu (orange metal) on the negative electrode.
