14. A solution which contains only one of the following cations: Ag+, Pb2+, or Cut is...
Suppose an unknown sample only contains Pb2+ and Cr3+ ions, but no other Group 2 cations. If an aqueous sample of this unknown is treated with NH4OH followed by NaOH, which observation will be true? A. a white precipitate will form, but the Pb2+ and Cr3+ ions will still make up a mixture B. a clear solution will be obtained, but the Pb2+ and Cr3+ ions still make up a mixture C. a blue-green gel will be produced, and the...
You have a solution that may contain up to two of the following 4 cations: Ag+, Pb2+, Cu2+, Ni2+. The initial solution is clear and blue. Upon adding NaCl, a white precipitate forms. You centrifuge and decant the solution, and heat the portion where the white precipitate is. Heating causes the white precipitate to dissolve. To the supernatant liquid, which is still blue, you add ammonia, resulting in a deep blue color. Which cations are present?
Be sure to answer all parts. A solution contains AgNO3 and Ba(NO3)2. What substance could be added to the solution to precipitate Ag+ ions, but leave Ba2+ ions in solution? Na2SO4 NaCl NaNO3 Na2S After removal of the Ag+ compound, what could then be added to the solution to precipitate the Ba2+ ions? NaCl Na2SO4 NaNO3
Question 14 1 pts A solution contains 0.1 M Ba2+ ions and 0.1 M Ag+ ions. Addition of an equal volume of a 0.5 M solution of which reagent will cause precipitation of a silver salt but not a barium salt? OKNO Na2SO4 Naci O NaNO3
A solution possibly contains Ag+, Pb2+, Bi3+, Fe3+, Ba2+ and Na+. You are about to begin the separation of the group I cations but no HCl is available. Would the following reagents be an acceptable replacement for separation of the group I cations in this sample? To justify your choice as yes or no, write the NIE for all precipitates you expect to form. If only group I solids are precipitating, that will be a “yes” and if more than...
200 mL of an aqueous solution contains 0.030 M concentrations of both Pb2+ and Ag+. If 100 mL of 6.0 x 10-2 M NaCl is added to this solution will a precipitate form? If so, what will the precipitate be? The Ksp values for PbCl2 and AgCl are 1.7 x 10-5 and 1.8 x 10-10]
