Chapter 3, Problem 154P(choose chapter or problem)
A major industrial use of hydrochloric acid is in metal pickling. This process involves the removal of metal oxide layers from metal surfaces to prepare them for coating.
(a) Write an equation between iron(III) oxide, which represents the rust layer over iron, and HCl to form iron(III) chloride and water.
(b) If 1.22 moles of \(\mathrm{Fe}_{2} \mathrm{O}_{3}\) and 289.2 g of HCl react, how many grams of \(\mathrm{FeCl}_{3}\) will be produced?
