In which cell does the anode have a positive charge?
Correct answer: C. Electrolytic cell
- A. Galvanic cell
- B. Concentration cell
- C. Electrolytic cell
- D. Both A and B
Explanation
Electrolytic cell uses external battery → anode is positive.

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.
