Electrolytic cell characteristics
Which statement is true of an electrolytic cell?
Answer C: explanation for every choice
A
Negative ΔG describes a spontaneous, galvanic cell.
B
In an electrolytic cell, the anode is positive because it is connected to the power source's positive terminal.
C
Correct. Electrolytic cells have ΔG > 0 and Ecell < 0, so energy must be supplied.
D
Oxidation always occurs at the anode.
TakeawayElectrolytic: ΔG > 0, external source, positive anode. Oxidation is always at the anode.
