Homework Help: chemistry

Posted by Andre on Monday, May 11, 2009 at 3:52pm.

Solid Na2SO4 is added to a solution which is 0.014 M in Pb(NO3)2 and 0.041 M in AgNO3. Assume the volume remains constant. Ksp = 2.0 10-8 for PbSO4 and Ksp = 1.2 10-5 for Ag2SO4.
(a) Which compound precipitates first?
1 PbSO4
(b) What is the concentration of the first ion precipitated when the second ion starts to precipitate?
