Question

Which of the following is true for an electrolytic cell?

• A. Reduction takes place at the anode
• B. The reaction is spontaneous
• C. Electrons start to flow from the cathode
• D. An electrolytic cell requires a salt bridge

Hint:

Electrons always flow from negative to positive terminal. In electrolytic cells, cathode is negative and anode is positive.

Answer 1

The Correct Option is C

In an electrolytic cell, the external voltage source pushes electrons into the cathode. This causes the flow of electrons to begin from the cathode and move toward the anode. Unlike galvanic cells, the electrolytic cell has a non-spontaneous reaction.
