Ex: Separation of Group 1 Cations (Pb+ and Ag+) 10 drops of unknown was place along with 6 drops of 6M HCl, centrifuge. 2 more drops of 6M HCl, centrifuge. Decant supernate, use precipitate and add 5 drops of cold water, centrifuge. Test for Pb2+ 15 drops of water to precipitate & put in hot water, centrifuge then decant supernate. repeat x2 Combine supernates and save precipitate for Ag+ analysis. Add 3 drops of 1M K2CrO4 to supernate. yellow precipitate...

A solution containing a mixture of metal cations was treated with dilute HCl and no precipitate formed. Next, H, S was bubbled through the acidic solution. A precipitate formed and was filtered off. Then, the pH was raised to about 8 and HS was again bubbled through the solution. A precipitate again formed and was filtered off. Finally, the solution was treated with a sodium carbonate solution, which resulted in no precipitation Classify the metal ions based on whether they...

A deep blue Group III unknown formed a blue-green precipitate when treated with NH_3/NH_4 Cl. The mixture was centrifuged and separated. The precipitate dissolved in NaOH to form a green solution. The solution turned purple when treated with BiO_3 in acid solution. All other tests were negative. What ion(s) is/are present? What ion(s) is/are certainly absent? Write net ionic equations for all observations mentioned above, using the ions that you have determined to be present. One of the reactions will...
