?In a galvanic cell the cathode is an \(\operatorname{Ag}^{+}(1.00 M) /
Chapter 20, Problem 20.11(choose chapter or problem)
In a galvanic cell the cathode is an \(\operatorname{Ag}^{+}(1.00 M) / \operatorname{Ag}(s)\) half-cell. The anode is a standard hydrogen electrode immersed in a buffer solution containing 0.10 M benzoic acid \(\left(\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{COOH}\right)\) and 0.050 M sodium benzoate \(\left(\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{COO}^{-} \mathrm{Na}^{+}\right)\). The measured cell voltage is 1.030 V. What is the \(\mathrm{p} K_{\mathrm{a}}\) of benzoic acid?
