Interpretation Introduction

Interpretation:

The $\left[{\text{H}}^{+}\right]$ and cell potential for $\text{Pt}\left(s\right)|{\text{H}}_{\text{2}}\left(\text{1}\text{atm}\right)|{\text{H}}^{+}\left(\text{?}\text{M}\right)\Vert {\text{Cl}}^{-}\left(1\text{M}\right)|{\text{Hg}}_{\text{2}}{\text{Cl}}_{\text{2}}\left(s\right)|\text{Hg}\left(l\right)$ at $25°\text{C}$ should be predicted.

Concept introduction:

A shorthand way of expressing the reaction that takes place in an electrochemical cell is said to be the cell notation. The half cells that is anode and cathode are separated by two bars, $\parallel$ which represents salt bridge. The left side of the two bars represents anode whereas the right side represents cathode. The phases of each cell are separated by single bar.
