?The cell in Figure 20.9 could be used to provide a measure of the pH in the cathode
Chapter 20, Problem 20.71(choose chapter or problem)
The cell in Figure 20.9 could be used to provide a measure of the pH in the cathode half-cell. Calculate the pH of the cathode half-cell solution if the cell emf at 298 K is measured to be +0.684 V when \(\left[\mathrm{Zn}^{2+}\right]=0.30 \mathrm{M}\) and \(P_{\mathrm{H}_{2}}=0.90 \mathrm{~atm}\).
Text Transcription:
[Zn2+] = 0.30 M
PH2 = 0.90 atm
