Objective The objective of this lab is broken into two parts. The first is to recognize the principles of flame ionization and atomic spectra. The second is to observe and thus further understand the line spectra for multiple elements or molecules as well as determine the correlation between emission spectra and atomic structure. Experimental Procedure Procedure 1: Observation of Line Spectra by Discharge Tubes Six discharge lamps were selected – argon‚ carbon dioxide‚ helium‚ hydrogen‚ iodine

The goal of this experiment was to measure spectroscope position to calculate wavelengths of line emission spectra while also using this data to determine the unknown mixture of the flame emission procedure of the experiment. The original hypothesis was that the spectroscope would show multiple different line emission spectra in which the ΔE would be negative there was an emission of light as the electron’s decreased in electron transitions. This hypothesis was proven correct‚ as well as‚ the unknown

effects tutorial‚ we’re going to learn how to create a fire text effect‚ engulfing our letters in burning hot flames. We’ll be using Photoshop’s powerful Liquify filter for most of the work on the flames themselves‚ but we’ll also be taking a look at the Wind filter‚ using adjustment layers to colorize the flames‚ layer styles for adding color to our text‚ layer masks for blending the flames with the letters‚ and more! Here’s the result we’ll be working towards: [pic] The final “fire text” effect

given a small beaker containing an unknown salt‚ x. The salt is crystalline‚ deliquescent and colorless. The student is asked to perform test and observation on the salt to determine the cation and anion present. HYPOTHESIS: Perhaps by using the flame test or reacting salt x with NaOH‚ or NH4OH the cation could be distinguished by observing the color changes or solubility while reacting salt x with H2SO4 or a mixture of copper turnings and concentrated sulphuric acid the anion of the salt could

Ocean County College Department of Chemistry Identification of Metallic Ions Purpose: The purpose of this lab exercise was to perform and observe the flame tests of some alkali and alkaline earth metal ions. When electrons in metallic ions are grounded‚ their configuration is stable. In other words‚ the loosely bound electrons in the valence shell of the atom are satisfied at their “low” energy state. They do not require to be balanced by emitting any type of radiation or receiving any

Gas Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to

required knowledge of solubility rules and demonstration of such in the laboratory setting for the first method of qualitative analysis. The second method of qualitative analysis was the performance of a flame test on various solutions to prove the presence of certain ions based on the color of the flame. In this experiment‚ unknown solution #1 was proven to contain lead (Pb2+) and barium

As this reaction continued for a long time‚ transparent solution turned into white opaque color and black precipitates were formed and floated. Step G: Record your observations with the flame and the hydrogen gas. When gently squeezing a small portion of the hydrogen gas into the flame‚ the flame showed small flash with a pop. Oxygen Step B: Describe the hydrogen peroxide and manganese reaction. As adding hydrogen peroxide to the test tube containing a few pieces of manganese metal‚ gas
