Pb(NO3)2(aq) 2 x 10-3 M and Na2SO4(aq) 2 x 10-3 M

Identify the ions that are present in each solution, and calculate their concentrations.

If 1 L of each solution are mixed, will a precipitate be formed? Why?

Calculate the ion prouct (Qsp) and compare with Ksp to determine if a ppt will form.
For (ion), it'sw mols/L soln except for a ppt. If a ppt forms, the concn of those ions is determined as a Ksp problem.
That's ion product.
