which of the following elements in glucose has zero oxidation state?
Correct answer: A. C
- A. C
- B. O
- C. H
- D. Both A and B
Explanation
The correct answer is Option A: C. In glucose, the element Carbon has a zero oxidation state. This is because in organic compounds like glucose, Carbon is often the central atom and typically maintains an oxidation state of zero due to its structural role. Options B, C, and D are incorrect because Oxygen and Hydrogen in glucose do not have zero oxidation states; they usually have oxidation states of -2 and +1, respectively, in organic compounds like glucose.

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.
