14.37 part a

When calculating the cell potential of the cell given in part (a) why are you allowed to omit Cl as is shown in the solutions manual?

This is possible because HCl is aqueous, and thus dissolves into H+ and Cl- ions. Since the other reactant/product is H2, the half reaction only involves the H+ ion from HCl.

HCl will dissolve into H+ and Cl- ions in solution. In the reaction, Cl- does not react with anything and therefore does not contribute to the balancing of the half reactions.
