Which of the following is reducing agent?
Correct answer: A. (COOH)2
- A. (COOH)2
- B. F2
- C. CO2
- D. HNO3
Explanation
(COOH)2 is the correct answer because it acts as a reducing agent by donating electrons to other substances in a reaction, thereby reducing them. In contrast, the other options-F2, CO2, and HNO3-are known for their oxidizing properties, meaning they tend to accept electrons rather than donate them.

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.
