Question: does pbcl2 form a precipitate?
Answer: In order for PbCl2 to precipitate, the concentrations of Pb2+ should be more than 0.0022M and that of Cl- is greater than 2x or 2(0.0022) = 0.0044M. ... (3) pH: Since Pb(OH)2 is an insoluble salt, decrease in pH (meaning more OH- in your solution), increases the solubility of PbCl2 since some Pb2+ are reacting with OH-.
