Question:

For the exercise in this topic, base your answers on the potentials listed in Table 6M.1 or Appendix 2B, with the exception of the reduction and oxidation of water at pH = 7: 2 HO (1) + 2 e H(g) + 2 OH (aq), E = O(g) + 4 H (aq) + 4e 2 HO (1), E = -0.42 V at pH = 7 +0.82 V at pH = 7 A total charge of 4.5 kC is passed through an electrolytic cell. Determine the quantity of substance produced in each case:

(a) The mass (in grams) of bismuth metal from a bismuth nitrate solution;

(b) The volume (in liters at 273 K and 1.00 atm) of hydrogen gas from a sulfuric acid solution;

(c) The mass of cobalt (in grams) from a cobalt(III) chloride solution. TABLE 6M.1 Standard Potentials at 25 C* Species Oxidized form is strongly oxidizing F/F Aut/Au Ce*+/Ce+ MnO
