Q. Select among the following statements that characterize a galvanic cell?
I: Oxidation occurs at the anode, which is negative.
II: Oxidation occurs at the anode, which is positive.
III. Reduction occurs at the cathode, which is positive.

Q. Assertion :Anode is the electrode at which oxidation occurs and cathode is the electrode at which reduction occurs. Reason: Anode and cathode in electrochemical cells and electrolytic cells have opposite polarity.

Q. Assertion :The electrode from which electrons emerge is called the cathode and is designated as negative. Reason: The electrode that receives electrons is called the anode and is designated as positive.
