please show all work!!!
1. A solution of .20M Na2CO3 is slowly added to a
mixture containing .35M Co^+2 and .45M Pb^+2
Ksp CoCO3 = 1.4 x 10^-3
Ksp PbCO3 = 7.4 x 10^-14

a. Will CoCO3 or PbCO3 percipitate first?
b. What percent of the initial concentration of the first ion to percipitate remaims in the solution when the other ion begins to percipitate?
