WebbIf we look at the reduction potentials for hydrogen ion and the iron two plus ion, the hydrogen ion at zero has a greater reduction potential than the F B two plus at negative 20.44 volts. Therefore hydrogen is going to be reduced and iron will be forced to be oxidized. The iron metal will be forced to be oxidized to plus. Webb21 okt. 2024 · The electrode potential or Ecell of the hydrogen electrode is which is equal to × V -----eqn 1. Here n=1 substituting the values in eqn 1. The hydrogen ion concentration was calculated as ; The electrode potential depends on the concentration of the substances, temperature, and pressure of the substances. fnf but everyone sings everything
