Pre Lab Questions 1 What equipment do you need to …
Pre-Lab Questions: 1. What equipment do you need to conduct the flame tests? Assorted metal salts, cotton swabs, watch glass, Bunsen burner, and water. 2. What is happening at the atomic level to give rise to the observed energy? The burning heats the metal salts, causing some of their electrons to go into higher energy levels, which are known as their “excited” states.

Flame Test- Strontium Chloride -
The flame test is preformed by burning a metal salt using a flammable liquid. Each chemical (in this case metal ion) gives off a characteristic color (seen here as changes in colors of the flames) when the electrons fall back down from their excited state and emit light at certain wavelengths (colors).

Color of chemicals - formulasearchengine
The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. What is seen by the eye is not the color absorbed, but the complementary color from the removal of the absorbed wavelengths .

Why is HCl used in a flame test? - Quora
In flame test compounds of some metals, in presence of conc. HCl, form different colored flames. In this test the compounds become volatile and then vapors form different colored flame’s. The purpose of using conc. HCl is to convert the compounds
Color of Transition Metal Complexes
Color of Transition Metal Complexes The variety of color among transition metal complexes has long fascinated the chemists. For example, aqueous solutions of [Fe(H 2O) 6] 3+ are red, [Co(H 2O) 6] 2+ are pink, [Ni(H 2O) 6] 2+ are green, [Cu(H 2O) 6] 2+ are blue and [Zn(H
