Solid Na2SO4 is added to a solution which is 0.012 M in Pb(NO3)2 and 0.048 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?

(b) What is the concentration of the first ion precipitated when the second ion starts to precipitate?

Hi Gregory.

Well, what a coincidence. Hello Stephon! My uncle's name is Stephon, but he lives across the country from me. Anyways, can someone please help me with this problem?

• Chemistry -

At least with part b. I figured out that part a is Pb(NO3)2

Lol same boat buddy.
