I have FeCl3,CuCl2 , and NaCl in a mixed solution. Display various methods to remove/separate Fe, Na, and Cu from the mixed solution. Ex: Voltaic cell, etc
1. A magnet can be used to efficiently separate a mixture of sand and very small iron pieces because the iron pieces will "bind" to the magnet but not the sand. When screening a library, what (in general) acts as the magnet? (One word)
What is the [Cl-] in a solution containing 0.333 M FeCl3 and 1.00 M CuCl2 ? 0.500 M 1.33 M 2.66 M 3.00 M 5.00 M

Let's assume you have a mixture of equal parts benzoic acid, sand and toluene that are intimately mixed together (the crude material is a mixture of solid and liquid). Propose a procedure to separate these three components using any of the chemicals commonly available (you've used all of the "common" chemicals in the lab by now) in the organic chemistry teaching laboratories and observing the typical limitations with the instruments and techniques (such as not being able to distill or...
