question 25 of 30
what is the cathode in an electrochemical cell?
a. the porous barrier between solutions
b. the electrode where reduction occurs
c. the electrode where oxidation occurs
d. the electrolyte that contains ions

Explanation:

In an electrochemical cell, the cathode is defined as the electrode where reduction takes place. Oxidation occurs at the anode. A porous barrier is for separating solutions while allowing ion - flow and the electrolyte contains ions but is not the cathode.

Answer:

B. The electrode where reduction occurs
