Metals are_?
Correct answer: A. Reducing agents
- A. Reducing agents
- B. Oxidizing agents
- C. Both A and B
- D. Dehydrating agent
Explanation
Metals are strongly electropositive, which means they tend to lose electrons easily. This property makes them effective reducing agents because, by losing electrons, they can cause other substances to gain those electrons and be reduced. Thus, metals facilitate the reduction of other substances while they themselves are oxidized. On the other hand, oxidizing agents gain electrons, which is characteristic of non-metals, not metals. Options C and D are incorrect because metals cannot act as both reducing and oxidizing agents simultaneously, and they do not function as dehydrating agents, respectively.

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.
