The purpose of this lab is to conclude the identity of two unknown metals by observing the colors produced by the two groups of metals and a transition metal. When observing colors we only see a small spectrum, this is what we call the Visible Spectrum. The visible lights we can see are in a “wavelength range of 400 - 700 nanometers (nm)” and in a shade variety of “violet through red” (Madigan). The most dangerous colors are gamma rays, due to them being the highest in frequency and “most energetic form of light.” The least dangerous is Radio, and it is low in frequency (Lake). Atoms in flame produce light when electrons in excited state return to ground state and energy is released as light.

Materials Needed For this Lab:

•Metal Compounds

•Bunsen Burner

•Striker

•Goggles

•Wire

•Spectrum Chart

•Well Tray

Before procedure is started, safety measures are met (such as no chemicals are being mixed, area is clear of unnecessary items, hair is maintained back, and safe attire with goggles are on). After safety was confirmed the procedure had begun. The striker was used to light the Bunsen burner. The motive was to produce the hottest flame possible. Than the wire was touched to …show more content…
The identity of the unknown salt is most likely a sodium based compound, because it was a bold orange shade similar to the flame of sodium chloride. One thing that kept going wrong was the stick catching on fire. When this would happen, the stick’s flame would change the color seen. Like when Barium Chloride wasn’t reacting right away, the stick caught on fire. This gave the conclusion that it was light yellow, until it was done over again to find that its flame was baby pink. I recommend redoing certain compounds over again to certify the exact color. My results would be even more descriptive and precise if I redid all of them, instead of a select

Bunsen Burner Lab Report

the ring stand was then placed on the table, and the Bunsen burner was placed on it. The ring clamp was then attached to the ring stand above the Bunsen burner. A clay triangle was then placed on top of the ring clamp in order to support the crucible. We then attached the Bunsen burner’s gas intake tube to the gas jet. Before lighting the Bunsen burner, I made sure that it was flat on the table. Matches were then used to light the Bunsen burner, and once…

Flame Test Lab Report

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…

Nahco3 Reaction Lab

The purpose of the NaHCO3 + HCl Reaction lab was to determine what two unknown gases were, then write a balanced equation for the reaction. Fiona and I started this lab by taking an evaporating dish and a watch glass, washing them with water, then drying them with a Bunsen burner. After that, we put 3.0g of NaHCO3 in the evaporating dish and covered it with the watch glass. Then, taking a dropper bottle of HCl, we put drops of HCl by slipping the pipet underneath the watch glass. We squirted HCl…

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…
