Standard electrode potential for hydrogen is taken as
Correct answer: D. Both A and B
- A. Standard
- B. Zero Volts
- C. Unity
- D. Both A and B
Explanation
A Standard Hydrogen Electrode (SHE) is an electrode that scientists use for reference on all half-cell potential reactions. The value of the standard electrode potential is zero, which forms the basis one needs to calculate cell potentials using different electrodes or different concentrations.The standard electrode potential refers to the potential difference between an electrode and the electrolyte when the concentrations of all the species involved in a half-cell are unity.

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.
