Purpose The purpose of this lab was to reinforce the examination of wavelengths in photons discharged from atoms as they move from high energy to low energy, atomic emmision. In this laboratory activity, the characteristic color of light emitted for calcium, copper, lithium, potassium, sodium, and strontium will be observed. Different elements produce different colored flames when placed in the fire of a Bunsen burner. After several tests for each solution it was determined that the accepted values for each solution, in order, were: Ba(NO 3) 2, yellow-green; Cu(NO 3) 2, green; LiNO 3 The free books on this site span every possible interest. FLAME TEST LAB Mrs. Cole Chemistry Introduction: Back in the 18th century, chemists began using flame tests to identify and distinguish elements. In the video, the scientist will expose seven different salts to a flame. 1. Observe the colour of light that is given off by each salt. Chemical Concepts Bookmark File PDF The Flame Test Lab Answers Flame Test Lab - Aidan Sterk's Digital Portfolio To do a flame test with each metal salt get a film of the solution of a salt inside the loop and bring it into the hottest part of the flame. Flame Test Lab Questions Answer Key: You could readily identify the elements that had obvious colors different form all the others- such as copper that gave off a blue/green color and lithium that gave off a … Unknown Crystals: Repeat the flame test steps using a small unknown crystal from the previous experiment as the sample. The prelab will be due the day before your lab section. Record your observations in your notebook and use the results of the previous tests to determine which metal ions (if any) are present in the unknown crystals. It was difficult to identify a couple of the elements that had colors that were similar. Ebooks and Text Archives: From the Internet Archive; a library of fiction, popular books, children's books, historical texts and academic books. Please watch the video below. In this laboratory activity, the characteristic color of light emitted for calcium, copper, lithium, potassium, sodium, and strontium will be observed. Table (20 pts.) After watching the video, please answer the questions below. If this produces poor color then try the edge of the burner flame. Page 1/4 the statement as capably as sharpness of this flame test lab answer key can be taken as capably as picked to act. Flame Test Lab Chemists began studying colored flames in the 18th century and soon used "flame tests" to distinguish between some elements. Hypothesis If the element (independent variable) is placed in the fire (controlled variable), then the Flame Test Kit Student Laboratory Kit Introduction Just as a fingerprint is unique to each person, the color of light emitted by metals heated in a flame is unique to each metal. Different elements produce different colored flames when they are being burned. CHEM 132 Lab 03 Western Carolina University 1 Chemistry 132 Lab 03 Flame Test and Electron Configuration Prelaboratory Exercise Go to Chem21Labs.com and complete the on-line prelab by answering the questions below. ... Pre-Lab Answers (18 pts)/ Answer in complete sentences. Flame Test Kit Student Laboratory Kit Introduction Just as a fingerprint is unique to each person, the color of light emitted by metals heated in a flame is unique to each metal. Reading the lab procedure will help you find the answers. Chemical Concepts We will be partaking in the flame test lab at a safe distance from the flames – behind your computer screens! Flame Test Chemistry Lab Answers Flame Test Lab Questions Answer Key: You could readily identify the elements that had obvious colors different form all the others- such as copper that gave off a blue/green color and lithium that gave off a bright red color. Lab Partner: Avery Martin 12/17/12 Flame Tests ABSTRACT: In this flame test experiment, seven different known solutions and three different unknown solutions were tested in a burner. Use a clean, uncontaminated wire from the provided beaker.
