Question

At what ph of hcl solution will hydogen gas electrode show electrode potential of -0.118v ,h2 gas being bubbled at 298k at 1 atm

Answer 1

Answer:

The electrode is dipped in an acidic solution and pure hydrogen gas is bubbled through it. The concentration of both the reduced form and oxidised form is maintained at unity. That implies that the pressure of hydrogen gas is 1 bar (100 kPa) and the activity coefficent of hydrogen ions in the solution is unity.

Answer 2
