Explain two ways that voltaic cells and electrolytic cells are similar and two ways that they differ.

Similarities:
•They both have cathode and anode charges.
•Cathode facilitates oxidation and the anode facilitates reduction.

Differences:
•Voltaic cells “work” autonomously, while electrolytic cells need an outside source of energy to work.
•While the voltaic cells’ redox reaction is uncalled-for, the electrolytic cells happen at a set time.

I hope I helped!
Chemistry is pretty hard to explain, so feel free to message me or leave a comment below if you need me to elaborate on my response. :)
