CHEMISTRY INVESTIGATION PLANNING AIM The aim of this experiment is to investigate the factors that effect the current flowing during the electrolysis of an aqueous solution of sodium chloride. In this experiment, I will keep the voltage, the volume of water, the mass of salt, temperature, and the distant between electrodes constant, while varying length of electrode in the water. VARIABLES In this experiment, I will only use one variable, although there are others to consider to ensure a fair test. As, if more than one factor is varied during the experiment, the results will not be reliable. These variables are: * The length of the electrode in the water * Temperature * Mass of sodium chloride * Volume of water * Distance between electrodes * Voltage During this experiment, I have chosen to vary the mass of sodium chloride in the solution. I will keep all the other factors constant. I will achieve this by using : * A ruler...
