Electrolysis Aim: The aim of this experiment is to test whether the length of time affects the amount of copper deposited on a cathode electrode. Apparatus needed * Power pack to supply the electrical current for electrolysis to take place. * Wires to join the components including an ammeter. * Multimeter to act as an ammeter to measure the current * Crocodile clips to clip electrodes to the beaker * Beaker, which will contain the electrodes and the copper sulphate. * Soft tissue paper to dry the copper sulphate off the cathode electrode. * Balance to weigh the cathode electrode * Stopwatch to measure the time the power is supplied * Copper sulphate, which will be the electrolyte. * Copper strips to be used as electrodes. Method 1. Weigh the cathode electrode and record the weight in a table. 2. Take a 100 cm3 beaker and fill 75 cm3 with the electrolyte, which is copper sulphate. 3. put a multimeter coming directly from the power pack...
