Investigating the rate of electrolysis.
An investigation to find out what factors affect the rate of electrolysis of a solution containing copper (II) ions.
Plan
It is known that by passing a constant electric current through a copper sulphate solution the passage of ions through this solution results in copper atoms being dissolved into the solution from the anode, which has a positive charge while positive copper, ions (cations) are also being discharged at the cathode which has a negative charge. Normally anions, which have a negative charge, are discharged at the anode.
