Standard Electrode potential is measured at?
Correct answer: C. 298K
- A. 273K
- B. 293K
- C. 298K
- D. 292K
Explanation
Option A is wrong because standard electrode potential is not measured at 273K. Option B is wrong because standard electrode potential is not measured at 293K. Option: C Standard electrode potential is measured at 298K, 1 atm or 1 M solutions. (Fact) Option D is wrong because standard electrode potential is not measured at 292K. It's value is fixed and the standard electrode potential is measured at 298K.

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.
