Q2. What is anode and cathod
Ans. 
Anode and cathode are electrodes used in electrochemical cells to facilitate the flow of electrons.
• Anode is the electrode where oxidation occurs and electrons are lost.

• Cathode is the electrode where reduction occurs and electrons are gained.

• In a battery, the anode is the negative terminal and the cathode is the positive terminal.

• In an electrolytic cell, the anode is the positive terminal and the cathode is the negative
