Flame

Chapter \ref{sootformation} briefly describes the background of soot formation, diffusion flame and counterflow flame. Chapter \ref{liigrund} presents the theoretical background of the measurement techniques used. In Chapter \ref{ch:LTT-HAB-Results}, the motivation of the experiment, the description of experimental setup, and experimental procedure are presented. In this chapter, the experiments include flame imaging, laser extinction, and TiRe-LII. The numerical simulation which is extensively…

data only “Substance C” has the color purple when we put on the flame test. The only basic substance that we have is “Substance B”. According to the picture that I have in my data, Na2Co3 is basic. So that means “Substance B” is Na2Co3 (Sodium Carbonate). Again if we look at the color flame picture that I have, we can see that Magnesium is white, and in my color flame test “Substance A” didn’t show any colors when we put on the flame. This means that since Magnesium is colorless or white…

Determination of Isoprenaline Hydrochloride Concentration Using Ultra Violet/ Visible Spectroscopy and Quantification of Sodium and Potassium Using Flame Spectroscopy Introduction In UV/VIS (ultraviolet-visible light) spectroscopy, light absorption as a function of various wavelengths gives data about electronic transitions within a solution [1]. The electronic transitions involve exciting an electron from one principle quantum state to another by the absorption of energy [2]. A change in…

Combustion is a chemical reaction between substances, according to www.scienceterms.com, "[Combustions processes] usually including oxygen and usually accompanied by the generation of heat and light in the form of flame. The rate or speed at which the reactants combine is high, in part because of the nature of the chemical reaction itself and in part because more energy is generated than can escape into the surrounding medium, with the result that the temperature of the reactants is raised to…

In this experiment, qualitative analysis was used to identify two cations. Lead was identified in Part A, barium was identified in Part B and different flame colors were observed with various metal chloride solutions in Part C. Formula unit, total ionic, and net ionic equations were written for the confirmation reactions for both lead and barium. If this experiment was repeated, barium could be confirmed by the yellow precipitate BaCrO4 after confirming that the solution was clear and any…

The princess with her right hand held high, directed the young man towards the right door. She yelled “The right one.” That old, brown, crusty door. It looks like they have been using it for millions of years. Of course the king has not lived that long but the kingdom (and the door)had been passed on to different kings whenever the past king died. The young man looked back at the princess. He had a scared look on his face. I mean wouldn't you? I bet you would if you had to choose one door or…

Scrying is an ancient form of divination. Scrying is the art of gazing into a reflective surface to gain information about the future. Many people use crystal balls, mirrors, candles and other surfaces as scrying devices for divinatory purposes. Although people use these reflective tools for seeing the future, many individuals don’t realize that these tools can also be used for contacting the dead. For more than one thousand years people have used scrying to connect with spirits. Individuals…

a wire loop for the flame test and adjust the burner so it is blue and no-luminous. Then, clean the wear loop by dipping it in concentrated hydrochloric acid and heat the flame until it glows. Pour about 10 milliliters of 10% sodium chloride solutions into a small beaker and for unknown use 2mL of unknown solution instead of sodium chloride. Dip the clean wire loop into sodium chloride solution and place the loop in the flame and record the observation. Third, potassium flame will be tested.…

If this experiment were to be repeated, another cation could be added for identification or a flame test could have been done with the solutions in Part A and Part B in order to determine the cation identity. In Part A of this experiment, after carefully following each procedure, lead was concluded to be the cation present in the #2 unknown aqueous…

What are products of combustion of alkenes? How do they account for the sooty and luminous flame? Ans: Alkenes are highly flammable with the presence of oxygen, and will give out product such as carbon dioxide gas and water. For example, ethylene burns as follow: C2H4 + 3 O2 → 2 CO2 + 2 H2O If the combustion of alkene is complete, it will give out a blue flame. On the other hand, as the number of atoms of carbon in the molecule increases, the combustion…
