Which of the following occurs in a $Cu-Zn$ cell?

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. 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. Which of the following statements are correct about voltaic cell?
(I) Chemical energy is converted into electrical energy.
(II) Electrons flow from anode to cathode.
(III) Oxidation occurs at anode.
(IV) Anode is negative and cathode is positive.

Q. Assertion :In an electrochemical cell, the electrode that is the site of reduction is called the anode.
Reason: Oxidation always occurs at the cathode.
