We test several chloride salts for their flame test colors we then determine the identity of two unknowns via flame test. The flame test is fast and easy but requires some practice to reliably produce and see the colors (some ions will be more intensely colored than others) to carry out a flame test, you will use a clean inert wire and a. The flame test was used to visually determine the identity of an unknown metal based on the characteristic color the salt turns a flame the heat of the flame excites the metal ions flame colors were produced from the movement of the electrons in the metal ions present in the compounds causing them to emit visible light. In5607 062007 catalog no ap5607 publication no 5607 flame test kit student laboratory kit introduction just as a fingerprint is unique to each person, the color of light emitted by metals heated in a flame is unique to each metal. Pre-laboratory assignment: flame tests of metal cations in this lab, you will perform flame tests of several different metal cations the characteristic colors observed are due to emitted electromagnetic radiation from the excited metal cations.
Flame tests are used to identify the presence of a relatively small number of metal ions in a compound not all metal ions give flame colours for group 1 compounds, flame tests are usually by far the easiest way of identifying which metal you have got. Flame tests were performed on damp cacl 2 and licl all other salts were dry wooden applicators need an additional flame source to burn just burning applicators alone did not produce a flame to be. To carry out flame tests with salts of lithium, sodium, potassium, barium, strontium and copper procedure light a bunsen burner and adjust it to obtain a blue flame dip the wooden splint in water and add one of the salt to it so it sticks on.
Though they have chosen chemistry as their career path, they feel much stress, when there is a need of a writing a chemistry lab report lab report is obviously intended for students of higher studies, and to help those advanced level students, we have made chemistry lab report help available all the time. Lab five flame test 3 report: flame tests data metal ion flame color (be very barium descriptive) ba 2+ calcium ca 2+ copper cu 2+ potassium k. Report abuse transcript of flame test lab flame test lab by:lupe gutierrez & krystal gonzalez when atoms/ions are in the ground state they are heated to high temperatures,some electrons absorb enough energy to jump to higher levels background info purpose observations pictures the purpose of the flame test lab is to see how different compounds.
Introduction to the flame test lab: the flame test lab was an in-class lab where we tested chemicals in the flames to see the wide range of colors in the color spectrum the secondary purpose of the lab was to identify unknown compounds that we would test and then guess as to what they were the flame test lab was done in several parts. What does a flame test indicate about the energy changes taking place among the electrons in a metallic ion indicate the specific energy change occurring in the ion why does a metallic ion produce a characteristic color in a flame test, regardless, of the compound used as the source of the ion. 5 once the wire is clean, dip it into one of the solutions, place the wire in the flame, and observe the color of the flame 6 clean the nichrome wire as directed in step 3, then repeat step 5 until all of the solutions have been tested.
Flame test lab report - download as word doc (doc), pdf file (pdf), text file (txt) or read online scribd is the world's largest social reading and publishing site search search. In this lab, students will conduct flame tests of several known elements, and then will try to identify an unknown element by its flame test please note: this lab is also sold in a bundled product contain 14 must-do physical science and chemistry labs. How are elements identified by using a flame test a metal salt is a compound of a metal and a nonmetal when dissolved in water, the metal and nonmetal atoms separate into charged particles called ions. The purpose of flame tests is to identify unknown metals and metalloid ionssafety is crucial in any flame test wear protective goggles, have a water source nearby and beware of ingesting or inhaling harmful odors.
In the flame test, if this energy has the form of visible light, the flame will produce a color characteristic of the element different elements have a unique color in its flame which. This video shows the positive results for the flame test section of megalab the flame test can be used to identify the following cations: li, na, k, ca, sr, ba, cu. Flame tests using metal salts description in this classic science experiment, students report on the colours produced when flame tests are carried out on different metal salts.
