A solution contains 0.10 M I- and 0.10 M CO32-. In an attempt to separate the ions, Pb(NO3)2 is slowly added to the solution.
(a) Identify the precipitates that could form and predict which precipitate will form first.
(b) When the second (more soluble) salt begins to precipitate, what is the concentration of the first ion to precipitate (I- or CO32-).
