Introduction Aim This is an investigation into how temperature affects the amount of copper lost from the Anode and gained on the Cathode during electrolysis. Electrolysis is... The chemical change by passing electric charge through certain conducting liquids (electrolytes). The current is conducted by migration of ions - negative ones from the Anode (positive electrode), and positive ones to the Cathode (negative electrode). Reactions take place at the electrodes by transfer of electrons in the direction of the current. In this case, copper electrodes in a copper sulphate solution are used. In the electrolysis of copper, copper atoms in the Anode become copper ions by losing electrons which go into the circuit. Cu - 2e --> Cu The positive ions are attracted to the negative Cathode but only copper ions are discharged. Cu - 2e --> Cu So this electrode gets coated with copper. ...
