if lead nitrate was added to sodium nitrate, how could one get the lead ions out of the sodium nitrate?

    We always "want to get the lead out" don't we? ;-).

    Add NaCl. That will ppt the Pb as PbCl2 or add Na2SO4 to ppt the Pb as PbSO4. If you are interested in purifying the NaNO3, however, I need to point out that this will contaminate the NaNO3 with NaCl or Na2SO4. It has removed the Pb but at the expense of contaminating the NaNO3.

    Thank you DrBob222!!!
