The electrode through which electrons enter the electrolytic solution is:
Correct answer: D. Cathode
- A. Both anode and cathode
- B. Anode
- C. Salt bridge
- D. Cathode
Explanation
The cathode is the negative electrode through which electrons enter the electrolytic solution. The chemical change occurring at the cathode is known as the reduction or gain of electrons. The anode is the positive electrode through which electrons leave the electrolytic solution. The chemical change occurring at the anode is known as the oxidation or loss of electrons.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
