Sep 04, 2015 · Flame Test Lab. PSI Chemistry Name_____ Introduction. The normal orbit or energy level of an electron in an atom of an element is known as its “ground state.” When atoms in the “ground state” are heated to high temperatures, some electrons may absorb enough energy to allow them to “jump” to higher energy levels.

In the instance of the popsicle flame, the three necessary components are present during the initial lighting of the fire. The heat generates from a separate flame, the lighter. The wood of the popsicle stick provides the fuel. Finally, the oxygen level present in the atmosphere is enough to sustain a flame.
5. Obtain a sample of an unknown solution. Record the number of the unknown! Perform a flame test and identiv the metallic ion present by the color of the flame. (It will not be a mixture.) HONORS CHEMISTRY FLAME TEST LAB-ANALYSIS QUESTIONS Ana.vsis Questions: 1. a) List the eements that gave the most easily identified colors. Explain.Decide on a hypothesis using the If/then format: During Lab: The experiment: Place a small amount of the solid compounds on an evaporating dish. Add 2 mL of methanol to dissolve the solid. Light a match and ignite the methanol. Watch the flame color and observe any changes from the control. Data and Observations.
Overall, the purpose of this experiment was completed. Discussion of Theory: The flame test is a procedure used to test quantitatively for the presence of certain metals in chemical compounds. This means that it is a procedure that includes lighting ionic compounds on fire, to see what color they turn once lit up. This lab was conducted in order to show students how flame color provided evidence of the presence of certain atoms withing the compound. In addition, two additional unknown substances were burned alongside the other given compounds; students were asked to identify the given substances using only observations of its flame.
This could affect the observation of the flame color observed for the next chemical. Post Lab Discussion Question: The flame test could be used to test unknown ionic compound powders that are hard to be determined with the human eye since some ionic compound powders are very similar in structure, transparency, and color. Calibrating a Thermometer - Lab needs: Title, data, calculations, conclusion (purpose, what you did and why, results, 2 sources of error) Solutions. Effect of Temp. on Solubility. Freezing Point Depression . Atoms & Periodic Table: Safe and Proper use of a Bunsen Burner. Flame Test Lab . Equilibrium: Activity - Establishing Equilibrium (make up ... Welcome to Mr. Baruch's Web Site. Here you will find information for both Parents and Students.

Oct 08, 2013 · The purpose of this lab was to observe the characteristic colors produced by certain metallic ions when vaporized in a flame. As well as to identify unknown metallic ions by means of its flame test. And to learn why light is shown as the color it is by the excitement of electrons jumping from one shell to the next. A flame test is a procedure used to test qualitatively for the presence of certain metals in chemical compounds. When the compound to be studied is excited by heating it in a flame, the metal ions will begin to emit light. Based on the emission spectrum of the element, the compound will turn the flame a characteristic color.
