Chapter 19, Problem 106E

Interpretation Introduction

To determine: The concentration of the solution, if E_cell is 1.22V.

The given electrochemical cell is as follows.

${\text{Pt(s)/H}}_{\text{2}}\text{(g, 1}{\text{.0atm)/H}}^{\text{+}}\text{(aq,1}{\text{.0M) // Au}}^{\text{3+}}\text{(aq,? M)/Au(s)}$
