Which has maximum oxidation number?
Correct answer: D. Mn (Manganese)
- A. N (Nitrogen)
- B. Cr (Chromium)
- C. S (Sulfur)
- D. Mn (Manganese)
Explanation
Manganese (Mn) exhibits a wide range of oxidation states, including +2, +4, +6, and +7. For example, in potassium permanganate (KMnO4), manganese is in the +7 oxidation state. This higher oxidation state (+7) reflects its capability to reach higher oxidation numbers compared to the other elements listed.

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.
