Chemistry 204 Practice Exam 3 – 40 minutes 1. Balance the following electrochemical equation in acidic condition using the smallest whole-number coefficient. What is the reaction quotient (Q) for the following reaction? Ag(s) | Ag + (aq) || ClO 4 - (aq), H + (aq), ClO 3 - (aq) | Pt (s), E = +0.40 V. 2. A lead electrode (cathode) in 0.010 M Pb(NO 3 ) 2 (aq) is connected to a hydrogen electrode (anode) in which the pressure of H 2 is 0.057 V at 25 °C. What is the pH of the electrolyte at the hydrogen electrode?
