It is known that by passing a constant galvanising current through an aqueous copper sulphate practice that the passage of ions through this solution results in copper atoms existence dissolved into the solution from the anode while positive copper ions (cations) cosmos discharged at the cathode. Normally anions are discharged at the anode. The experiment carried out aimed to monitor the quantity of Copper (Cu) metal deposited during the electrolysis of Copper Sulphate solution (CuSo4) using Copper electrodes, when supreme variables were changed. It was considered that the following factors could affect the deposition of Copper metal on the cathode. 1. Time 2. Current 3. Temperature 4. Molarity/Concentration of Solution 5. step of Solution 6. Size of Electrodes 7. Distance amid the electrodes 8. The surface of the electrodes The snip was chosen because it is an easy quantity to poster and record, whilst at the same eon mainta ining the other variables at a constant level. The other factors could be observed in later(prenominal) experiments, should prison term allow. PREDICTIONS It is possible to hazard that the blood will be directly comparative between the time the current flows and the good deal of Copper deposited on the Cathode (negative electrode). I can then predict that if I double the time of the experiment, I will therefore be doubling the charge.

This affirmation can be support by both of Faradays Laws. Faradays early Law of electrolysis states that: The plentifulness of both grammatical constituent deposited du ring electrolysis is directly proportional t! o the itemize of coulombs of electricity passed Faradays foster Law of electrolysis states that: The mass of an element deposited by one Faraday of electricity is equal to the atomic mass in grams of the element divided up by the number of electrons required to discharge one ion of the element.
