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

Laboratory Report: Flame Colors of Metals Abstract The experiment about flame color of metals demonstrates how electrons jump into their excitedstate from their ground state as it came in contact with heat. As it return to its lower energy state‚it emits the absorbed energy in the form of light. A platinum or nichrome wire was dipped into aconcentrated HCL and was heated to clean it. The wire was dipped into different salt solutionsand heated in order to determine the metallic ion’s color and wavelength

CONCLUSION After many class lab days‚ I concluded my unknown was Calcium Carbonate due to results from the Flame Test and Anion I Test. Throughout our lab days‚ my friends would help me determine various odors and colors of the substances which allowed me to confirm my answer. Also‚ I looked select test results up on the internet to see if they matched my observations. On our first lab day‚ I received my bottle and noticed a white precipitate in the bottom therefore‚ my unknown was insoluble. I

Othello :-an analysis of the color imageries used in the play “Othello” Imagery‚ in a literary text‚ occurs when an author uses an object that is not really there‚ in order to create a comparison between one that is‚ usually evoking a more meaningful visual experience for the reader or it may be defined as the use of more vivid figurative language to represent objects‚ actions‚ or ideas. And the color imagery is one of the prominent in them ‚it refers to the use of colors by the author to describe

Emission Spectra & Flame Tests Intro The emission spectrum is used in modern chemistry to help further studies of wavelengths and the spectrum. When a metal in a compound reacts in a flame and produces a color‚ it helps to show the strongest color in the emission spectrum. The purpose of performing these operations on the flame was to see how different metals would react. Using a spectroscope‚ it is possible to observe the line emission spectrum produced by sunlight‚ artificial light‚ and

In this lab‚ we tested the effect of flame on different chemical solutions. In order to do this‚ we used a wooden stick soaked in a metal and nonmetal solution‚ hovered it over a bunsen burner‚ and recorded the color that the flame changed to. The seven solutions we tested were lithium chloride‚ strontium chloride‚ calcium chloride‚ sodium chloride‚ barium chloride‚ copper chloride‚ and potassium chloride. However‚ we had another four additional solutions‚ which had unknown chemical composition
