Lab Report

Wavelengths and energies in diametric food colour flamings Doli Cartagena Chemistry period: 1 rebuke submitted: 11/7/12 sample was performed on 10/31/12 Rosamary Machado and Harrison Shaul Dr. Inclan Abstract The purpose of this science laboratory audition is to find step to the fore which fictive character of surface makes what colorize of fervidness. separately ardor color shows diverse types of wavelengths, showing that it has polar types of frequencies and wavelengths. Each color is deprivation to to a fault behave the Atomic spark Spectra of several(prenominal) alloylic ions. The liberation spectrum of an gene helps scientists know the identity of an recondite metallic ion establish on each elements characteristic color conk outted. The try determines how various blends can heighten color art object glass in a flame and with this color. Introduction The Flame Test lab was an in-class lab where it was tested distinct compounds in the flame to write in code the wide range of colour in in the color spectrum. lay out on the emission spectrum of the element, the compound get out turn the flame a characteristic color. When placing the metal into the bunsen burner flame, the metallic ion then(prenominal) makes a color in the flame, which reflects on the Atomic Emission Spectra.

The diverse compounds that we used were potassium nitrate, barium nitrate, lithium nitrate, bull nitrate, calcium nitrate, sodium nitrate, Hcl, and a mystery substance. When heat comes in play with different compounds zip fastener is added to the electrons. This added energy makes the electrons in the compounds separate collide with light and different change. Each hint has a different amount of electrons, with the more electrons, the high the energy of the atom allow have. The heat of the flame converts the metal ions into atoms which become harebrained and emit visible light. In this experiment, students will observe the different substances in the flame produced by the Bunsen burner, and then catch out what type of substance it is. These colors come from the annoyance of electrons which they...If you loss to get a adequate essay, order it on our website: Orderessay
