Standard Electrode Potential is measured at temperature:
Correct answer: B. 298K
- A. 348K
- B. 298K
- C. 20K
- D. 235K
Explanation
Standard Electrode Potential is defined as the potential difference between a metal electrode and its solution of ions at standard conditions. Standard conditions include:Temperature: 298 K (25°C)Pressure: 1 atm (101.3 kPa)Concentration: 1 M (1 mol/L)

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.
