Question 1

Write the formula of the strongest reducing agent. given the following standard reduction potentials in acid solution
O2 + 4H+ + 4e–→2H2O
E° = +1.23 V
Sn4+ + 2e–→Sn2+
E° = +0.13 V
Zn2+ + 2e–→Zn(s)
E° = –0.76 V
 


Question 2

You wish to electroplate a metal utensil with a surface area of 736 cm2 with gold to give an average thickness of 0.025 mm over the entire surface. Starting with a solution of excess Au3+ and applying a constant current of 14 A, how long will it take to electroplate the utensil? The density of gold is 19.3 g/cm3.
