Use the following half-cells with their reduction potentials to answer the electrochemistry questions below: Half-Reaction Al³+ (aq) + 3 e Al(s) HO₂ (aq) + H₂O(l) + 2 e 3 OH(aq) Ag+ (aq) + e Ag(s) Co2+(aq) +2e^ = Co(s) Zn²+ (aq) + 2 e → Zn(s) Eºred (V) +1.66 +0.88 +0.80 +0.28 -0.76
Question 4 A galvanic cell is setup with the following two half-cells: • A 250.0 mL solution of 0.15 M aluminum nitrate with a platinum electrode. A 250.0 mL solution of 0.85 M cobalt(II) nitrate with a cobalt electrode. e) (2) Determine the cell potential that will be initially measured for this galvanic cell. f) (2) How much mass is gained/lost by the cobalt electrode after the cell reaches equilibrium. ● g) (1) If it takes this galvanic cell 2.00 hours to reach equilibrium, how much current would this cell generate (assume a constant current during this time)?
