Unformatted text preview: AP Chemistry Redox/Electrochemistry Review Questions 1. Given the following notation for an electrochemical cell: Pt (s) H 2(g) H + (aq) Ag + (aq) Ag (s) What is the balanced overall (net) cell reaction? 2. Consider a voltaic cell based on the following cell diagram: Pt (s) Pu 3+ (aq) , Pu 4+ (aq) Cl 2(g) , Cl- (aq) Pt (s) Given that the standard cell emf is 0.35V, and that the standard reduction potential of chlorine is 1.36V: Cl 2 + e- Cl- E = 1.36V What is the value of the standard electrode potential E Pu 4+ /Pu 3+ ? Pu 4+ + e- Pu 3+ E = ? 3. Will H 2(g) form when the following metals are placed in 1.0M HCl? a. Fe __________ b. Ag __________ c. Cu __________ d. Sn __________ 4. Given the following standard reduction potentials in acid solution: O 2 + 4H + + 4e- 2H 2 O E = +1.23V Sn 4+ + 2e- Sn 2+ E = +0.13V Zn 2+ + 2e- Zn (s) E = -0.76V a.
