Question

mn(s) 2h (aq)→mn2 (aq) h2(g)mn(s) 2h (aq)→mn2 (aq) h2(g) express your answer in bolts using two decimal places.

Answer 1

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.
