ou are tasked with determining a way to identify the following ions in solution: Na+, Ni2+, Ag+, and Pb2+. What techniques would you use to selectively precipitate out the ions and how would you separate the precipitates from the supernatant layers? Your arsenal of compounds to use for the separation is KCl, KCH3COO, and KOH. Clearly define each step.
A 1 L solution contains 0.25 M Ni(NO3)2 and 0.25 M Cu(NO3)2. A. Can the metal ions be separated by slowly adding Na2CO3?

The solubility of Ag2CrO4 (Ksp = 1.2 x 10-12) is several times greater than that of AgCl (Ksp = 1.82 x 10-10), so the red precipitate cannot form until all the chloride ions have effectively been removed from the solution. If a student uses 1 mg of K2CrO4 Aas an indicator for 100 mL of sample solution, what is the concnetrion of chloride ion in the solution when the red precipitate (Ag2CrO4) starts to form?

A solution contains 1.0 × 10−4 M Cu+ and 2.0 × 10−3 M Pb2+. If a source of I− is added gradually to this solution, will CuI (Ksp = 1.27 × 10−12) or PbI2 (Ksp = 7.1× 10−9) precipitate first?
