Electrolysis experiment. Electrodes (crocodiles clips) attached to filter paper dipped in a solution of copper sulphate (blue) and connected to a power supply. Passing an electric current through copper sulphate separates the copper from the sulphur and oxygen. When filter paper is used,instead of electrodes,the result is that bands form on the filter paper moving towards each electrode,with the colours depending on the solution undergoing electrolysis | |
