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^-.

Lead chloride cannot be directly prepared by adding hydrochloric acid because lead chloride is insoluble in water. When hydrochloric acid (HCl) is added to water, it dissociates into H+ and Cl- ions. These ions are soluble in water and remain as free ions in the solution.

However, when lead chloride (PbCl2) is added to water, it does not fully dissociate into Pb2+ and 2 Cl- ions. Instead, it forms a solid precipitate. This is due to the relatively low solubility of lead chloride in water.

To prepare lead chloride, an alternative method is needed. One common way is to react lead metal or lead oxide with hydrochloric acid. The reaction is as follows:

Pb + 2 HCl -> PbCl2 + H2

In this reaction, the lead metal or lead oxide reacts with hydrochloric acid to form lead chloride and hydrogen gas. This reaction can be carried out in a fume hood due to the release of toxic hydrogen chloride gas (HCl). Once the reaction is complete, the lead chloride can be separated from the solution through filtration or other methods.
