An electrochemical cell of notation Pd|Pd2+ || Ni2+ |Ni has Eo = -1.45 V. If we know that the standard reduction potential of Ni2+ /Ni is Eo = -0.25 V, what is the standard reduction potential for Pd2+/Pd?
hey guys. this is my working
Ecell=reduction-oxidation
therefore Pd is anode therefore oxidisin and Ni is cathode therefore reducin.
so i sub this into formula -1.45=-0.25-oxidation therefore oxidation=-1.20 however the answer is positive 1.20, why is this? anyhelp would be good thanks
