QUALITATIVEANALYSISREPORTPROJECTAName:Rukiya UmojaDate:04/29/16Sample Number: 10Project A: Pb2+ions are presentConfirmation Tests: To 1 mL of the unknown, 10 drops of 6 M HCl were added. Noprecipitate formed. After stirring the mixture, it was centrifuged for 30 seconds. 1 dropof 6 M HCl was added. No more precipitate formed. The supernatant (SB) was transferredinto a clean test tube.To SI.1, 3 drops of 6M acetic acid and 5 drops of 1M K2CrO4were added. A yellowprecipitate formed confirming the presence of Pb2+ions.To PI.1, 2.5 mL of hot water and 2 drops of 6 M HCl were added. PI.1 was then heated in aboiling hot water bath for 3 minutes and centrifuged. The decantate was then removed.
