An inventor proposes using a SHE (standard hydrogen electrode) in a new battery for smartphones that also removes toxic carbon monoxide from the air:

Anode:\({\bf{CO(g) + }}{{\bf{H}}_{\bf{2}}}{\bf{O(l)}} \to {\bf{C}}{{\bf{O}}_{\bf{2}}}{\bf{(g) + 2}}{{\bf{H}}^{\bf{ + }}}{\bf{(aq) + 2}}{{\bf{e}}^{\bf{ - }}}\;\;\;{\bf{E}}_{{\bf{anode }}}^{\bf{^\circ }}{\bf{ = - 0}}{\bf{.53\;V}}\)

Cathode:\({\bf{2}}{{\bf{H}}^{\bf{ + }}}{\bf{(aq) + 2}}{{\bf{e}}^{\bf{ - }}} \to {{\bf{H}}_{\bf{2}}}{\bf{(g)}}\;\;\;{\bf{E}}_{{\bf{cathode }}}^{\bf{^\circ }}{\bf{ = 0\;V}}\)

___________________________________________________________

Overall:\({\bf{CO(g) + }}{{\bf{H}}_{\bf{2}}}{\bf{O(l)}} \to {\bf{C}}{{\bf{O}}_{\bf{2}}}{\bf{(g) + }}{{\bf{H}}_{\bf{2}}}{\bf{(g)}}\;\;\;{\bf{E}}_{{\bf{cell }}}^{\bf{^\circ }}{\bf{ = + 0}}{\bf{.53\;V}}\)

Would this make a good battery for smartphones? Why or why not?

Step by step solution

01

Step 1: Standard hydrogen electrode:

It serves as a reference electrode against which all electrode potentials are measured. When \(1\)atm-pressure hydrogen gas is adsorbed on a platinum electrode soaked in \(1M\) HCl at \({25^ \circ }C\), it is a typical hydrogen electrode with a potential of \(E0 = 0\)volt.

02

Find the ideal battery for the smartphone:

• This battery would not be ideal for smartphones because the usual voltage of smartphone batteries is between \(1.25\;{\rm{V}}\) and \(1.5\;{\rm{V}}\) this battery produces a voltage of \(0.53\;{\rm{V}}\).
• However, given the right concentrations of reactants, a functioning battery can most probably be constructed.
