The required Standard electrode potential is +1.18V.

What is Standard electrode potential?

  • The difference in voltage between the cathode and anode is known as the standard cell potential. View Cell Potentials for more details. All of the standard potentials are determined using 1 M solutions, 1 atm, and 298 K.
  • The difference between the two electrodes, known as the standard cell potential (Eocell), creates the cell's voltage.
  • The equilibrium potential can be measured using the standard electrode potential.
  • The potential of a cell under normal state circumstances, which are roughly represented by concentrations of 1 mole per litre, is known as the cell's standard state potential.

Given that,

Mn+2H^+-- > Mn^{+2}+ H_2

E°cell , E\°_{2H^+/H_2}-E\°_{Mn^+2/Mn}

0.0-(-1.18)=+1.18V

=+1.18V

The required Standard electrode potential is +1.18V.
