Investigating for Cations and Anions :: Papers

analyse for Cations and Anions In this experiment I will investigate what cations and anions are comprise in various compounds. This will include carrying out a qualitative analysis, because I need to find out what type of cations and anions are in that location and not quantitative analysis, which includes finding out how much of each element there is. Safety Points Wear glasses Wear gloves Do not mix more than two resolvents Only mix the antecedents listed by the instructor Handle the chemicals with extreme care Put the chemical solutions into a test-subway system which is resting on a test-tube holder Follow school lab condom procedures. Materials assorted chemicals. Test tubes. Boiling tubes. Pipettes. Test tube holder. Bench mat. Method I first copied the chemical solutions listed. I put on some gloves and safety glasses. I got a test-tube holder and placed five test-tubes in it. Cations I added the test solutions bull Chloride to the test-tube. To this I added a few drops of Sodium hydroxide solution. by and by the few drops a pale blue precipitate of Copper Hydroxide appeared that indicated the presence of Cu ions. I then added the test solution Iron Chloride to the second test-tube. To this I added a few drops of Sodium Hydroxide. After that a brown precipitate of Iron Hydroxide appeared that indicated the presence of Fe ions. To the 3rd test-tube, I added the solution Sodium Hydrogen Carbonate and added subjugate Sodium Hydroxide. I quickly covered the test-tube with a delivery tube and put the end of it into another test-tube with limewater. The limewater turned a cloudy/ milklike colour which indicated that there was CO present. Anions In the 4th test-tube, I poured the solution Copper Chloride into the test-tube.
