problem set chapter 19 Student: ___________________________________________________________________________ 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. Which choice lists all of the following species that can oxidize H 2 O to O 2 (g) under standard-state conditions? (2H 2 O(l) O 2 (g) + 4H + (aq) + 4e - ) MnO 4 - (aq), Cl 2 (g), Pb 2+ (aq), Cl - (aq), Ag + (aq) 3. Consider the following standard reduction potentials in acid solution: The strongest oxidizing agent listed above is 4. A battery is constructed by placing copper and lead electrodes in contact with 1.0 molar CuSO 4 (aq) and Pb(NO 3 ) 2 (aq) solutions, respectively. If sulfuric acid is then added to the Pb(NO 3 ) 2 solution, thereby forming a precipitate of PbSO 4 , what will happen to the cell potential? 5. A current of 2.50 A was passed through an electrolytic cell containing molten CaCl 2 for 4.50 hours. How many moles of calcium metal should be deposited? 6. How many grams of nickel would be electroplated by passing a constant current of 7.2 A through a solution of NiSO 4 for 90.0 min? 7. Complete and balance the following redox equation. MnO 4 - + H + + Br - Mn 2+ + Br 2 + H 2 O (acidic solution) The sum of the smallest whole-number coefficients is 8. Aluminum does not corrode as does iron, because
