Suppose that you precipitate Hg22 Hg 2 2 from a solution containing 0 01 M Hg2(NO 3 )20 01 M Hg 2 (NO 3 ) 2 and 0 01 M Pb(NO3)20 01M Pb(NO 3 ) 2 by adding I l If you want to know whether a small amount of Pb2 Pb 2 coprecipitates with Hg2I2,Hg 2 I 2 should you measure Pb Pb in the mother liquor (the solution) or Pb Pb in the precipitate Which measurement is more sensitive By sensitive, we mean responsive to a small amount of coprecipitation

Question: Suppose that you precipitate Hg22+Hg 2 2 +from a solution containing 0.01 M Hg2(NO 3 )20.01 M Hg 2 (NO 3 ) 2 and 0.01

Suppose that you precipitate Hg22+Hg₂²+from a solution containing 0.01 M Hg2(NO₃)20.01 M Hg₂(NO₃)₂and 0.01 M Pb(NO3)20.01M Pb(NO₃)₂ by adding I-l^- . If you want to know whether a small amount of Pb2+Pb²⁺ coprecipitates with Hg2I2,Hg₂I₂ should you measure _PbPb in the mother liquor (the solution) or _PbPb in the precipitate? Which measurement is more sensitive? By “sensitive,” we mean responsive to a small amount of coprecipitation.
