RESEARCH QUESTION: Could flame tests be useful in identifying the identity of elements? Background: When metals are heated, their valence electrons become excited and jump up to . Introduction: In this lab you will conduct a flame test of 3 unknown solutions. You will measure wavelengths of each sample and You will measure wavelengths of each sample and then use . It’s your job to help her figure out which is which. This is what we know: 1. All of the chemicals are salts. A salt is any compound made of chloride (a halogen) and an element from groups 1 and . Sep 19, · Flame Test Lab Questions Answer Key: 1. 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. identity of an element. This technique of confirmation is called a flame test. Metallic atoms and ions possess electrons that are easily “excited”. This being the case, the flame test is a quick, simple technique to help identify a particular metal. 1. Nov 30, · Flame Test Demonstration Purpose: to observe flame colors of some metal ions and relate the data to electron transitions Procedure: 1. Watch the video of the flame test demonstration. 2. As you observe the colors, make appropriate observations in the data table below. Flame Test Lab Questions Answer Key: 1. 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. 2. It was difficult to identify a couple of the elements that had colors that were similar. 3. It’s your job to help her figure out which is which. This is what we know: 1. All of the chemicals are salts. A salt is any compound made of chloride (a halogen) and an element from groups 1 and 2 on the periodic table (Alkali & Alkaline Earth metals). 2. Some chemicals can be identified by the flame they produce. All. In this experiment, you will perform the flame tests used to identify several metallic elements. SAFETY FIRST! In this lab, the solutions you will be using contain harmful materials. Avoid skin contact with these chemicals. Observe all precautions, especially the ones listed below.
