Changing the material of an electrode affects:
Correct answer: A. Nature of reaction
- A. Nature of reaction
- B. Temperature of reaction
- C. None of these
- D. Pressure of reaction
Explanation
During electrolysis, when electric current flows through the circuit, the electrodes gain or lose electrons. This losing or gaining of electrons determines whether the reaction taking place on either electrode will be reduction or oxidation. Hence, changing the material of the electrode affects the nature of the reaction.

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.
