Question

where does oxidation occur in an electrochemical cell?
a. cathode
b. anode
c. electrolyte
d. power source

Explanation:

In an electrochemical cell, oxidation is the loss of electrons. Oxidation occurs at the anode, where electrons are released into the external circuit. The cathode is where reduction (gain of electrons) occurs. The electrolyte allows ion - movement and the power source is not the site of oxidation.

Answer:

B. Anode
