Aim: I want to find out the affect current has on copper sulphate solutions as I increase the voltage. Prediction: I predict that as I increase the amount of current, the rate of extraction will speed up. In this case, if I start off low, the result will be minimum, whereas, as I steadily increase the current the result will change and maximise. As a result, due to this increase of current the rate of electrolysis will fasten, producing more and more copper in the negative cathode. Hypothesis: Electrolysis is a chemical reaction caused by the passing of an electric current through an electrolyte, which in my case is copper sulphate solution. In general, electrolysis is the decomposition of a compound into its element. To convey the electricity to the solution we use electrodes, where the end product is gathered. The element should on either the anode or the cathode; this basically...
