Question:

What happens if you use Copper Electrodes in an Electrolysis Reaction, using an Aqueous Solution of Copper Sulphate? What happens to the Masses?

Author: eric_galvao



Answer:

-Everything will seem the same, until you notice the Mass of the Anode Decreasing, and the Mass of the Cathode Increasing. -This is because Copper from the Anode, is Transferred to the Cathode -This can happen because the Electrical Supply makes the Electrons rip Away from the Copper atoms, in the Anode making them enter the Solution as Cu²+ -And then it gets Attracted to the Negative Electrode, which is the Cathode and it makes them back to Copper Atoms. -And Since Copper is less Reactive than Hydrogen, it will Stay There.
