An electrochemical cell is based upon which reaction?
Correct answer: B. Redox reaction
- A. Acid-base reaction
- B. Redox reaction
- C. Nuclear reaction
- D. Neutralization reaction
Explanation
An electrochemical cell is based on a redox reaction. Redox reactions involve the transfer of electrons between species. In an electrochemical cell, this transfer of electrons is facilitated through the separation of the oxidation and reduction half-reactions, which occur at different electrodes.

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.
