Flame Test Lab Morgan Chemistry CP 5/30/14 Abstract- In the flame test lab‚ the flame test was performed to excite the electrons in the samples and observe the color of the flame. The flame emits a color because each element has an exactly defined emission spectrum‚ which one can use to identify them. For example‚ NaCl was highlighter yellow‚ Sr(NO3)2 was sun orange‚ CuCl2 was turquoise‚ LiCl was neon red‚ KCl was solar flare yellow‚ and BaCl2 was Voldemort green. Introduction- In Bohr’s

and is titled The Magdalene with the Smoking Flame. It was done in the year 1640‚ using oil paint on canvas. La Tour did this painting in France. It is currently located at the Los Angeles County Museum of Art‚ but is not currently being displayed to the public. The lines in this work of art are of a large variety. On the right side of the painting a lot of the objects are horizontal. The woman though is sitting up vertically‚ along with the flame. There are a few diagonal lines also‚ for example;

A flame test is conducted when an element is burned and the flame produces a color different the starting flame color. When the coffee stirrer was put into the flame‚ the element’s atoms (from the solution of the stirrer) left the original level of energy. When the atoms fell back to ground level‚ they released photons in the form of colored flame. Using the flame test‚ unknown compounds can be identified when they are burned since each element has a specific color. (Douma‚ 2008). The color

11th D Flame Test Intro: The flame test is a procedure used by chemists to identify the presence of specified metal ions‚ based on the color the flame that appears along with it when it ’s heated. Our flame test was in lab class‚ where the main aim was to tested different solid metals in the flame in order to observe the wide variety of colors those chemicals also sometimes compounds (by mixing them) they produced‚ the second one was to identify unknown metals based on their flame color

Flame Test Lab Your company has been contracted by Julius and Annette Benetti. They are worried about some abandoned‚ rusted barrels of chemicals that their daughter found while playing in the vacant lot behind their home. The barrels have begun to leak a colored liquid that flows through their property before emptying into a local sewer. The Benettis want your company to identify the compound in the liquid. Earlier work indicates that it is a dissolved metal compound. Many metals‚ such as

Lab 20: Flame Tests Purpose/Objective: The ground state is the normal electron configuration of atoms or ions in an element. When atoms or ions in ground state are heated to a higher temperature‚ some electrons absorb enough energy to move them to higher energy levels. This is known as the excited state. However‚ the excited configuration is unstable‚ and the electrons must return back to their positions in the lower energy level. As they return‚ the energy that was previously absorbed is now emitted

Lab Questions: Are flame tests valuable for detecting metal ions present in a mixture of metal ions? Flame test may not be valuable for detecting individual metal ions present in a mixture of metal ions. Although each metal ion emits a different color of light‚ which corresponds to a certain wavelength of light‚ the presence of some elements may over power the flame and cause only certain wavelengths to be seen. For example‚ if sodium is present

this‚ rinse it with distilled water from the wash bottle‚ dip it into the Hydrochloric Acid‚ and place it in the burner flame for a few moments. 4. Take note of the color of the flame when the wire is clean. This is the color you should see after each cleaning. 5. Once the wire is clean‚ dip it into one of the solutions‚ place the wire in the flame‚ and observe the color of the flame. 6. Clean the Nichrome wire as directed in step 3‚ then repeat step 5 until all of the solutions have been tested.

Background In the Flame test lab we took a simple wire‚ looped it‚ and rinsed it in HCL (Hydrochloric Acid ). Then we dipped the wire in the different samples provided. The samples provided were Sodium‚Potassium‚Calcium‚ Barium‚ Strontium‚ Lithium ‚ and Copper II. Finally we put the wire loop into the flame of the bunsen burner. The flame erupted into many different colors for each specific sample. We then used the colors we recorded to find the two unknown samples given to us. But the question
