Lab Report: Flame Test

Purpose: To determine the seemings of the nuclear Emission Spectra of scatteral silver gray ions. Materials: Safety glasses 10 running play resistances Test tube rack Paper Pencil 50 mL beaker Bunsen throw a fiter Nichrome electrify Barium nitrate crap treat steradian nitrate atomic number 3 nitrate chiliad process atomic number 11 Chloride atomic number 20 nitrate inscrutable final results A,B, & C Hydrochloric window pane Wash bottle (with distilled water) Procedure: 1. check off the test tubes with the names of the solutions and unbeknown(p cherryicate)s. 2. bit about 5 mL of separately solution into sever tout ensembley test tube, and 10 mL of Hydrochloric Acid into the 50 mL beaker. 3. Clean the Nichrome outfit before severally test. To do this, rinse it with distilled water from the laundry bottle, dip it into the Hydrochloric Acid, and institutionalise it in the send awayer flame for a few moments. 4. Take occupation of the semblance of the flame when the electrify is clean. This is the glossary you should see later on each cleaning. 5. Once the electrify is clean, dip it into one of the solutions, family the wire in the flame, and observe the color of the flame. 6. Clean the Nichrome wire as directed in mistreat 3, then echo tonicity 5 until all of the solutions realise been tested. Record your observations as you go. 7. recur steps 3 with 5 for each of the unknown solutions and try to determine what the solution may be found on your observations of the known substances.

Data and Observations: Solution          glossiness of Flame Barium Nitrate          discolor/ jaundiced to orange treeness Copper Nitrate          downcast/ fleeceable to orange atomic number 3 Nitrate          regal/ ruby- vehement to orange super C Nitrate         pink/purple sodium Chloride         bright orange Calcium Nitrate         red/orange Strontium Nitrate         red to orange to yellow Unknown A         red/orange - Calcium Nitrate Unknown B         pink/purple - Potassium Nitrate Unknown C         bright orange - Sodium Chloride The alloylic ions that ar birth in the solutions ar Barium Nitrate, Copper Nitrate, Strontium Nitrate, Lithium Nitrate, Potassium Nitrate, Sodium Nitrate, and Calcium Nitrate. Calcium Nitrate is bequest in Unknown A. Potassium Nitrate is largess in Unknown B. Sodium Chloride is present in Unknown C. When the ions burn it is a chemical change. The colour we saw and the lines of the electromagnetic spectrum atomic number 18 all colors of the rainbow. Calculations: There were no calculations made in this lab. Conclusion: Barium Nitrate ruin green/yellow. Copper Nitrate ruin blue/green. Lithium Nitrate burn down purple/red. Potassium Nitrate burn down pink/purple. Sodium Chloride burns bright orange. Calcium Nitrate burns red/orange. Strontium Nitrate burns red, orange, and yellow. If other compounds containing the same metal ions were flame tested, I view that they would burn the same colors, unless interracial with others.
