2:55 how come the positively charge copper ions goes thru the circuit thru the anode? doesnt anode only attract anions which are negatively charged compared to the copper ions which arent

[@sn_wfl4ke]

he's talking about the electrons going through the circuit. since electrons oppose the direction of current flow. the electrons then meet the cathode where they undergo reduction and neutralize the copper ions into solid forms.
the electrons go through the circuit. not the copper ions!

Thank you sir

Do i have to use a copper sulfate solution or can it just be salty water?

[@salamancahouse]

You have to use a soluble copper salt [such as copper sulphate]. The electrolyte must contain copper 2+ ions in solution otherwise the cathode wont get electroplated

[@HinaThreefaced]

@@salamancahouse thanks

[@PhantomMight]

imma be one of those 3 hours before commentors, but hey thanks.

What is now the fate of the SO3 ions

[@mdrpublishing]

Hi Oladele. The SO42- ions remain in solution. The copper atoms in the anode are oxidised to copper ions instead of the sulphate ions. If a stainless steel anode wer used OH- ions would be oxidised in preference to the sulphate ions resulting in the release of oxygen
