You are given a solution that may contain Ba2+ and Pb2+ ions. You can assume that no other ions are present. Devise a method for separating, isolating, and confirming these ions. You can select from the techniques used in this lab, and any others that you might find appropriate. There are several valid alternative approaches to answer this question. Provided your approach appears logical and complete, it will be acceptable.

Assume that you have an aqueous solution containing Pb2+, Na+, Fe3+, and K+ ions. You need to devise a way to separate the ions from one another. Which of the following statements is NOT correct regarding your method? A) Na+ and K+ ions can be separated by precipitation of potassium with sulfate ions.                        B) Pb2+ ions can be precipitated as PbCl2 by adding a source of chloride ions.                        C) Iron(III) ions can be precipitated as Fe(OH)3 by adding...

Can Ba2+ be separated from Pb2+ by the addition of Na2SO4? Assume the starting solution is 0.10 M in both cations and use whatever concentration of sulfate you like. (Ksp of PbSO4 = 1.3 x 10-8), while that of( BaSO4 = 1.5 x 10-9). Calculate how much of the first cation to precipitate is left in solution when the second starts to fall out of solution. Is it less than 1% of the initial present?

Please do not attempt to solve if you can not answer all!!! THE ENERGY BAR INDUSTRY In 1986, PowerBar, a firm in Berkeley, California, single-handedly created the energy bar category. Positioned as an athletic energy food, it was distributed at bike shops and events that usually involved running or biking. The target segment was the athlete who needed an efficient, effective energy source. Six years later, seeking to provide an alternative to the sticky, dry nature of the PowerBar, a...
