Consider a voltaic cell that consists of a Ag+/Ag half-cell and a standard hydrogen electrode (SHE) at 25°C. a. What is the balanced chemical reaction? b. What is E°cell? c. Calculate AG and K for the reaction. d. Given that the experimental emf is 1.02 V, [Ag(aq)+] = 1.0 M, and PH2,(g)= 1.0 atm, calculate the pH at 25 °C. e. Given that the experimental emf is 1.02 V, [Ag(aq)+] = 0.5 M, and PH2,(g) = 0.8 atm, calculate the pH at 25 °C. Subject: Analytical Chemistry
