The equations are as follows...
At the anode (positive electrode): 2O2− ---> O2 + 4e−
At the cathode (negative electrode): Al3+ + 3e− ---> Al

5.3 write ionic half-equations for the reactions at the electrodes in aluminium extraction.
If you are looking at this post I assume you know what the electrolysis of aluminium oxide is and the implications, if you do not know, this may help... 5.2

The right equation for cathode (negative electrode) is : Al3+ + 3e- → Al
ReplyDeleteGood spot thank you!! mustve just been a typo hahaha, will change it now:)
