20l COURSEWORK2000/2001 SAM MOED CHEMISTRY: THE ELECTROLYSIS OF COPPER (II) SULPHATE SOLUTION USING COPPER ELECTRODES 1.PLANNING: A. POSSIBLE FACTORS WHICH COULD AFFECT THE MASS OF COPPER DEPOSITED OR LOST: There are in fact many factors that could affect the mass of Copper lost or deposited on the electrodes: * The current intensity or strength * Time (for how long the current is passed) * Concentration of the CuSO4 solution * Size and surface area of the plates * Depth of immersion of plates * Temperature of solution * Distance between plates * Voltage The factor that is to be investigated in this experiment is one of these: current intensity and so all the others will have to be kept constant to be sure that any correlation between the increase in current and the increase in mass is due to the former only. B. Electrolysis in general Electrolysis is the chemical decomposition of an ionic compound by the passing through it of an electric current. The...
