Homework Help: Simple precipitation question?

  1. Mar 16, 2010 #1
    Hi there.

    I'm just wanting to know the most important reason why barium chloride is chosen over lead chloride as the precipitation agent when trying to determine, by gravimetric analysis, how much sulfate is in a sample.

    I think it's probably due to BaCl2 having a higher solubility, but I just want to confirm.
    In the experiment the BaCl2 (or PbCl2) is added to a heated solution containing the sulfate ions.

    What about the solubilities of PbSO4 and BaSO4?
