A solution containing 0.100 M AuCl4 and 0.100 M CI is subjected to a continuous current of 6.00 A to deposit Au(s) in one electrode and Cl₂ gas on the other electrode. The reaction involved is : 3Cl¯ (aq) + AuCl4 (aq) →1.5 Cl2(g) + Au(s) + 4Cl¯( (aq). Given F= 96,500 C/mol e (or 96,500 J/V-mol e) and the standard reduction potential values: Cl₂ + 2e → 2Cl¯ AuCl₂ + 3e → Au +4Cl¯ a. Write the oxidation half reaction. b. Write the reduction half-reaction. Write the shorthand cell notation. Eᵒred_(V). 1.360 1.000 C. d. Calculate the standard cell potential involved. e. Calculate the mass, in grams, of Au (At. mass= 197) that is deposited in one of the electrodes after passing the 6.00 A current for 245 seconds.
