Investigating for Cations and Anions :: Papers

Investigating for Cations and Anions In this experiment I will investigate what cations and anions are present in various compounds. This will include carrying out a qualitative analysis, because I need to find out what type of cations and anions are on that point and non quantitative analysis, which includes finding out how much of each element there is. Safety Points Wear glasses Wear gloves Do not aggregate more than two solutions Only mix the solutions listed by the teacher custody the chemicals with extreme care Put the chemical solutions into a visitation-tube which is resting on a test-tube holder Follow school lab safety procedures. Materials Various chemicals. render tubes. Boiling tubes. Pipettes. Test tube holder. Bench mat. Method I commencement copied the chemical solutions listed. I sit on some gloves and safety glasses. I got a test-tube holder and placed five test-tubes in it. Cations I ad ded the test solutions sloven Chloride to the test-tube. To this I added a few drops of sodium hydroxide solution. afterward the few drops a pale blue precipitate of Copper Hydroxide appeared that indicated the presence of Cu ions. I then added the test solution cast-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 tertiary test-tube, I added the solution Sodium Hydrogen Carbonate and added Dilute 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/milky tint which indicated that there was CO present. Anions In the 4th test-tube, I poured the solution Copper Chloride into the test-tube.
