Purpose The hypothesis is that the color of light emitted by a metal is unique. Each metallic salt will show a different heat exposure, and will be a different color. Going into this lab the objective is to prove that the color of light shown by many metallic salts and two unknown substances is exclusive and unique. Consequently, this will help with the identification of the two unknown materials. The lab can explain the composition of objects that people may see or use everyday, including fireworks. The metallic salts will be shown and inevitably each present a new flame. Materials

The purpose of this lab was to identify the two unknown substances and prove that each color of light emitted by a metallic salt is unique. The lab proved that each metallic salt color when put into a flame is distinctive. Consequently, the lab also proved that every day materials can also be used within labs. Unknown substance number one was found to be barium chloride and unknown substance number two was found to be potassium chloride. Moreover, each metallic salt gives off a special distinctive color.
Questions (Double Spaced)

The energy of colored light (ROYGBIV) increases in the order of the “rainbow.” List the metallic elements used in this lab in increasing order of the energy of light they emitted. The order of the substances that was found during the lab is lithium chloride, strontium chloride, potassium chloride, potassium chloride (unknown number two), sodium chloride, calcium chloride, barium chloride, barium chloride (unknown number one) and, copper chloride.
When a glass rod is heated in a Bunsen burner flame it turns the flame around it a shade of yellow/orange. What does that tell you about the composition of the glass? The shade of the glass indicates that there is sodium located in the

Flame Test Lab Report Essay

Purpose: The purpose of the lab was to identify the unknown metallic ions by exciting the electrons of other materials and comparing the color of flame with the color of the unknown substances. Materials and Procedure: A q-tip dampened with distilled water is rolled in one of the salts. Place the end of the q-tip with the salt in a lit Bunsen burner flame. Then, record the substance excited and the corresponding flame color. Repeat the process until all salts have been tested. Finally…

Flame Emission Spectroscopy Test Lab Report

The sample of the dissolved metal compound was tested and compared it to common metal compounds using the flame emission spectroscopy test. By using this method, the metal compound inside the containers is Potassium Nitrate. In the flame emission spectroscopy test, scientist tested for the color metals give off when reacting to heat. Metal compounds give off color when added to the heat. This happens because when heat is added electrons get excited, and jump energy levels in the electron cloud.…

Project 1: Lab Report Frank Johnson CHM2045L Section 001 June 5, 2018 Introduction: We discover some elements in nature that are unknown and it’s difficult to know what elements are in these compounds. We can take a random substance that is unknown from nature and figure out what it is composed of by running simple lab tests. A real-world example of this would be how doctors examine a patient’s blood to see if they have overdosed off of drugs. By using the procedures in this project 1 lab, we can…
