H2 gas in SHE is filled at a pressure of
Correct answer: A. 760mm of Hg
- A. 760mm of Hg
- B. 750mm
- C. 780mm
- D. 800mm
Explanation
The standard hydrogen electrode uses hydrogen gas at a pressure of 1 atm, which corresponds to approximately 760mm of Hg. Maintaining this pressure ensures consistent conditions for potential measurements.

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.
