In an electrolytic cell current flows ?
Correct answer: B. From anode to cathode outside the cell
- A. From cathode to anode in outer circuit
- B. From anode to cathode outside the cell
- C. From cathode to anode inside the cell
- D. both B & C
Explanation
In the external circuit of an electrolytic cell, conventional current flows from the positive anode toward the negative cathode, opposite to electron flow. Students may choose cathode to anode by following electron movement, but conventional current and electron flow have opposite directions.

About Redox Reactions
Redox reactions involve oxidation and reduction occurring together, with electrons transferred between species or oxidation numbers changing. The topic covers assigning oxidation states, identifying oxidizing and reducing agents, balancing redox equations by oxidation number or half-reaction methods, and connecting chemical changes with galvanic and electrolytic cells.
