I would like to understand what happens exactly when i make electro cleaning to a copper oxide object.i browsed a lot in the web and i didn't find appropriate explanation.
I make a solution of vinegar+some salt.
I connect the copper oxide object to the negative voltage(as a cathode)and a copper wire to the positive voltage(as an anode).
I understand that in the solution there are hydrogen,oxygen,chlorine,soduim and copper ions,ch3oo- and h2o.
When i close the circuit i understand that hydrogen bubbles create around the copper object,oxygen bubbles create around the copper wire(maybe also chlorine)and the object get rid of the oxygen atom during the process.
What is actually happens?:
Does the anode-wire dissolved and get eaten in that process?does it release copper ions?
Does the copper oxide object(cathode),besides than get rid of the oxygen,also plated with a kind of material,maybe with the copper that might dissolved from the anode wire?
Does the oxygen ion release from the copper oxide object,even,before i close the circuit?
I will be very appreciate to hear an expert explanation what is happening exactly in that process.
Thanks in advance.
