Question

Metal with high concentration of $O_2$ on its surface acts as :

• A. an anode
• B. a cathode
• C. an electrolyte
• D. none of these

Answer 1

The correct option is A an anode

In a standard battery, the anode is the positive terminal and the cathode is the negative terminal. The anode of a battery is involved in an oxidation reaction. Electrons that reside in the anode are transferred into the electrolyte as a result of this reaction. The cathode of a battery is involved in a reduction reaction. so, the Oxygen will be liberated at anode and will get reduced at cathode, as metals are electron donor, it will act as an anode
