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 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. Please watch the video below. Page 1/4 In the video, the scientist will expose seven different salts to a flame. Different elements produce different colored flames when they are being burned. 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. 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. Different elements produce different colored flames when placed in the fire of a Bunsen burner. 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. If this produces poor color then try the edge of the burner 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 … Hypothesis If the element (independent variable) is placed in the fire (controlled variable), then the In this laboratory activity, the characteristic color of light emitted for calcium, copper, lithium, potassium, sodium, and strontium will be observed. the statement as capably as sharpness of this flame test lab answer key can be taken as capably as picked to act. 1. After watching the video, please answer the questions below. Observe the colour of light that is given off by each salt. It was difficult to identify a couple of the elements that had colors that were similar. Unknown Crystals: Repeat the flame test steps using a small unknown crystal from the previous experiment as the sample. Flame Test Lab Chemists began studying colored flames in the 18th century and soon used "flame tests" to distinguish between some elements.
