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

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

Flame test: AIM: To determine which part of the salt is responsible for the characteristics in the flame. HYPOTHESIS: If we introduce a metal salt in the blue flame of the Bunsen burner‚ then the colour given off by the flame is due to the metal part of the salt. METHOD: (1) With a heat proof mat under the Bunsen burner‚ turn the gas on and light up the Bunsen burner with matches. (2) Pour enough Hydrochloric acid into a beaker. (3) Using your wire‚ dip it into the beaker containing Hydrochloric

How does the chemical being burned affect the color of fire? Why do you think each fire burns a different color? The colors of the flames are are due to the different chemicals and substances. The bright yellow-orange of most wood fueled flames is because of the sodium‚ and when it’s heated‚ it emits the glow of the fire. The blue in some wood-fueled flames is because of the carbon and hydrogen emit a blue and purple aura. How are the colors produced by a chemical when it burns related to the atomic

3/5/14 3/5/14 Flame Test Purpose In this experiment I will learn how to perform and observe the flame tests of some alkali and alkaline earth metals and be able to identify and unknown chemical by the color of the flame Procedure I placed about 0.5 mL of 8 different chemicals into 8 different places in the 24-well plate. I then lit the handy wick to keep a flame burning. I soaked a cotton swab in the first chemical and moved the cotton swab in and out of the flame rapidly to see the flame color change

Investigate Flame Colors of Different Cations When they were heated by Fire. & Testing changes of cations using sodium hydroxide (NaOH) aqueous Aims & Objectives Different characteristic cations will form different colors when they are burned or added base. In these two experiments‚ scientist took some sample of barium hydroxide (Ba (OH) 2·H2O)‚ ferric chloride (FeCl3·6H2O)‚ copper chloride (CuCl2· 2H2O)‚ calcium chloride anhydrous (CaCl2)‚ potassium carbonate crystal (K2CO3· 2H2O)‚

Laboratory Report on the Reaction of Flames Towards Medals  Introduction The purpose of the flame lab was to identify a set of flame-test color standards for selected metal ions‚ relate the colors of a flame test to the behavior of excited electrons in a metal ion‚ observe spectral lines using diffraction grating‚ and to identify an unknown metal ion by using a flame test. My hypothesis for the lab was that most of the flames when sprayed with a solution will be a orange-red color. The
