Question

The pressure of hydrogen required to make the potential of hydrogen electrode zero in pure water at 298K?​

Answer 1

Answer:

25°C

Explanation:

Actually, it does . The absolute electrode potential for the standard hydrogen electrode (SHE) is estimated to be 4.44 ± 0.02 V at 25 °C. However, for the ease of comparison with other electrode potentials, the SHE is given a reference potential of 0 V at all temperatures.
