Q2) Write the products name and formula of white ppt after adding 15M NH3 and few drops of (NH4)2CO3 with mixture of cations.
I am assuming you have precipitated all cations till Group IV.
Then the Cations that will be precipitated are Ba2+, Ca2+ and Sr2+.
All of them will precipitate as carbonates Ba2+ as BaCO3,Ca2+ as CaCO3 Sr2+ as SrCO3.
Barium Carbonate=> BaCO3
Calcium Carbonate => CaCO3
Strontium Carbonate => SrCO3.

3. Suppose after adding HCl to ppt 16, you do not have any black solid. What, if anything, should you do to test for Co2 and Ni*? Qual Scheme: Group III: Co?(pink), N1" (green), Fet+ (yellow), Cr" (blue-grey), Mn(pink), AP (colorless), Zn? (colorless). Unknown B Solution: Use 10 dps of unknown sample and 10 dps of H20 and go to Procedure for Group III. Procedure for Group II: Add 2 dps NHCl soln, add 6M NHOH until just basic to...
Aluminum ion in solution reacts with water to form aqueous hexaaguaaluminum ()ion. Write this reaction below, remember phases. Aluminum is more likely to form a hydrated complex than the other four ions remaining in solution, because of its relatively small size and high charge To separate the Group B2 ion, the solution first is made basic by adding ammonia. In the presence of this weak base the pH is adjusted to 9-10 and the group B ions form insoluble hydroxides....

Experiment 8 Name: Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of cach reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms...
