Flame Test Lab Question: When a compound is placed in the flame of a burner‚ what happens to the color of the flame? Hypothesis: When the compound is placed in the flame‚ the flame changes color depending on the chemical compound. When they’re heated‚ they gain energy and changed color sometimes. Safety Requirements for this Lab: Wear goggles at all times. If you want to remove them to write in your notebook you may sit at a table in the center of the room. When you sit down remove them

Flame Test Lab Introduction/Purpose: When a certain amount of energy is supplied within an atom‚ the electrons of that atom begin to move up the levels of electron configuration. This level of energy is called a quantum. The object of this experiment was to examine the movement of electrons up and down energy levels through the use of given elemental substances. With heat supplying a large amount of energy‚ the properties of the elements caused them to give off a certain color or tone of

In this lab‚ we tested the effect of flame on different chemical solutions. In order to do this‚ we used a wooden stick soaked in a metal and nonmetal solution‚ hovered it over a bunsen burner‚ and recorded the color that the flame changed to. The seven solutions we tested were lithium chloride‚ strontium chloride‚ calcium chloride‚ sodium chloride‚ barium chloride‚ copper chloride‚ and potassium chloride. However‚ we had another four additional solutions‚ which had unknown chemical composition

Timothy Johns Christian Howard Wan Huang 10/18/12 Flame Test Lab Introduction Spectroscopy is the study of the electromagnetic radiation emitted or absorbed by atoms and molecules. These studies are very helpful in determining an unknown element‚ given the fact that all elements burn a different color. The flame colors vary because of the different amounts of energy the elements give off. This lab is made for the learner to determine the identity of two unknown elements. Hypothesis If

Lab 20: Flame Tests Purpose/Objective: The ground state is the normal electron configuration of atoms or ions in an element. When atoms or ions in ground state are heated to a higher temperature‚ some electrons absorb enough energy to move them to higher energy levels. This is known as the excited state. However‚ the excited configuration is unstable‚ and the electrons must return back to their positions in the lower energy level. As they return‚ the energy that was previously absorbed is now emitted

Laboratory Report on the Reaction of Flames Towards Medals  Introduction The purpose of the flame lab was to identify a set of flame-test color standards for selected metal ions‚ relate the colors of a flame test to the behavior of excited electrons in a metal ion‚ observe spectral lines using diffraction grating‚ and to identify an unknown metal ion by using a flame test. My hypothesis for the lab was that most of the flames when sprayed with a solution will be a orange-red color. The

Laboratory Report: Flame Colors of Metals Abstract The experiment about flame color of metals demonstrates how electrons jump into their excitedstate from their ground state as it came in contact with heat. As it return to its lower energy state‚it emits the absorbed energy in the form of light. A platinum or nichrome wire was dipped into aconcentrated HCL and was heated to clean it. The wire was dipped into different salt solutionsand heated in order to determine the metallic ion’s color and wavelength
