Question

Fan + Medal

Answer 1

What is a key difference between an electrolytic cell and a voltaic cell?

Answer 2

The anode is where the oxidation takes place.



The cathode is where the reduction takes place.



There are two half-reactions.



There is an outside energy source.



The electrons move from the anode to the cathode.

Answer 3

In an electrolytic cell you need an outside source of energy like a battery while in a voltaic cell the reaction occurs simultaneously, or without help. The other major difference is that in a electrolytic cell, the flow of electrons is from positive(cathode) to negative(anode). In an voltaic cell the flow of electrons is from negative(anode) to positive(cathode).

Answer 4

So I'd go with "The electrons move from the anode to the cathode."

Answer 5

yup :)
