The Quick and Easy Experiments thread.
Source : Heinmann science 3 for Queensland Regan Spence Page 21 Experiment 5- electroplating Aim- To use electrolysis to electroplate an iron nail with copper. Materials- -200ml Copper sulfate solution -piece of copper -large iron nail -accurate scales (very important) - 6 V power supply - 2 leads with alligator clips -steel wool Method- 1 . Clean the peice of copper and the nail thoroughly with the steel wool. 2. Record the masses of the piece of copper and the nail. You could use a table to do so. 3. Connect the circuit as shown. Make sure the nail is connected to the negative terminal of the power supply. 4.Turn on the power, be very careful not to let the nail touch the copper as it will spark. 5. Take them both out and record the differences in mass. 6. note the appearence of both the nail and the copper now its obvious that electroplating of the copper onto the iron occurs here mine didn't quite add up (most likely due to the scales) but it could have also been from the copper sulfate solution. You can actually watch the electroplating happing with this one!!
