Why can't lead chloride be directly prepared by adding hydrochloric acid to lead(ous) oxide?
PbO is not soluble in HCl and what little dissolves forms PbCl2 directly (but only in small amounts) and that sticks to the surface and impedes the production of more PbCl2. It isn't that it can't be prepared; it's just that it can't be prepared in larger quantities. The reaction is just too slow. The main impediment is that PbO is not soluble. If in solution the Pb^2+ could react directly with Cl^-.
