Question 1

A metal object is to be gold-plated by an electrolytic procedure using aqueous AuCl3 electrolyte.  Calculate the number of moles of gold deposited in 3.0 min by a constant current of 10. A.
◦ 6.2 × 10–3 mol
◦ 9.3 × 10–3 mol
◦ 1.8 × 10–2 mol
◦ 3.5 × 10–5 mol
◦ 160 mol

Question 2

Aluminum does not corrode as does iron, because
◦ Al does not react with O2.
◦ A protective layer of Al2O3 forms on the metal surface.
◦ Al is harder to oxidize than is Fe.
◦ Fe gives cathodic protection to Al.
◦ The electrical circuit cannot be completed on an Al surface.
