Standard electrode Potential is denoted by?
Correct answer: C. E°
- A. E
- B. E-1
- C. E°
- D. A
Explanation
The standard electrode potential, denoted by 'E°', represents the potential of an electrode reaction under standard conditions, which include 1 molar concentration, 1 atm pressure, and pure substances at 25°C. This notation is important as it provides a reference for comparing the tendencies of different redox reactions. Options 'E' and 'A' do not include the degree symbol (°) and therefore do not indicate standard conditions. 'E-1' incorrectly suggests an inverse or reciprocal, which is not applicable here.

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.
