Identification of Metallic Ions

Ocean County College subdivision of Chemistry Identification of Met allic Ions blueprint The purpose of this lab exercise was to make and observe the fervor experiments of purely floor and alkaline earth metal ions. When electrons in all-metal ions ar grounded, their configuration is st fitting. In early(a) words, the loosely bound electrons in the valence shell of the atom be live up to at their low talent state. They do not require to be balanced by emitting any lawsuit of radiation or receiving any supererogatory electrons.However, these stable, grounded electrons in the metallic ions become provoke to high power levels due to the front of heat, thus losing their stability. They absorb heat muscle, just counteract by releasing the intent energy to become grounded once again. This released energy comes in the form of electromagnetic energy. round of the released heat energy is in the visible light region. The metallic ions being heat disperse unique colors which are characteristic ranging from a lower energy (red) to a high energy (violet) and some colors in between.We can involve much about the element were working with by simply spy the color flame up that is produced. Flame tests are a common confirmation test to discern specific elements. Procedure I began the lab by preparing a in effect(p) work area and the required metallic ions. The ions used in this lab were as follows Barium treat, atomic number 20 process, Cupric treat, atomic number 3 treat, honey oil nitrate, Sodium Nitrate, Strontium Nitrate, and an apart(p) resoluteness. I placed 0. 5 mL of sodium nitrate into a salutary on the 24-well plate, recording its location.I placed 0. 5 mL of the other 7 solutions in 7 other wells on the plate, recording their locations as well. I blotto the tip of a cotton wipe up into the solution of sodium nitrate and passed the plastered end through the flame some(prenominal) times until I noticed a color change. I recor ded all observations in the Data Table chart below. I repeated these steps for the other 7 solutions. Data Table Observations Column1 Column2 aluminiferous Ion Flame Color Sodium Nitrate Orange/yellow Strontium Nitrate indistinct Crimson RedPotassium Nitrate Violet Barium Nitrate Green/Yellow Lithium Nitrate Deep Crimson Red Calcium Nitrate Orange Cupric Nitrate Blue/Green Unknown (Lithium) Deep Crimson Red Conclusion The flame test was a success and satisfied my learning objective. Since every metal gives the flame a different color, I was able to identify most of the given elements with a slight populate for error. The unknown solution gave off a deep level red glow which could have been every strontium nitrate or lithium nitrate.I went with the latter after doing the test several(prenominal) times, comparing the glows. Dimming the light in the room helped tremendously to get a bettor idea of the true color of each flame. Although this method isnt perfect to identify more un known ions due to the slight variations of colors, it does the job. The low energy metallic ions take on were Strontium and Lithium. The moderate energy ions were Sodium, Barium, and Calcium. The higher energy ions were Copper and Potassium.
