    Purpose: The purpose of this experiment is to observe the colours produced when the solutions of metal ions are heated to high temperatures‚ then to explain the results in terms of the energy levels of the metal ions. Lastly‚ to use the flame colours to identify a series of unknowns. Hypothesis: Substance being tested Predicted flame colour NaCl(s) Yellow NaCl Red-Orange NaNO3 Dark Orange LiNO3 Red Sr(NO3)2 Dark Red KNO3 Blue-Indigo Ba(NO3)2 Yellow-Green Cu(NO3)2 Green Ca(NO3)2

    Laboratory 3: Molarity Of Saline Solution Data: Please write your observations about the appearance of the solution. 1. Normal Saline- The solution appeared clear at the start with slight particles showing‚ once adding the salt it still appeared clear. 2. Nasal Irrigation Saline- Solution appeared cloudy once adding the salt and baking soda‚ then it turned semi-clear about 30 secs later; it was more concentrated than the normal saline. Results: 1. Determine the molar mass of NaCl. Show the workup

    Determining the Concentration of an Unknown Solution Graph: The effect of concentration of CuS04 * 5H20 on transmittance. I solved for my unknown by plugging in “y” as my given transmittance value‚ which was 85.0. y = -278x + 100.12 .85 = -278x + 100.12 -99.27 = -278x X = .357M (concentration) The relationship between the transmittance values and the concentration is an indirect relationship. Whenever the concentration increases‚ the transmittance decreases. It can also be reversed

    Title of the Experiment: determination of densities Introduction The density of a sample of matter represents the mass contained within a unit volume of space in the sample. For most samples‚ a unit volume means 1.0 ml. The units of density‚ therefore‚ are quoted in terms of grams per milliliter (g/ml) or grams per cubic centimeter (g/cm3) for most solid and liquid samples of matter. Density is often used as a point of identification in the determination of an unknown substance. The density

    Discussion: The experiment lacked a proper control - While the experiment could not answer the research question‚ this does not disprove the possibility for the choice of bread to affect blood glucose levels; the obtained results were simply not sufficient to prove a connection. This might be due to several reasons‚ but as the experiment lacked a control subject which the other values could have been compared to‚ the results are completely unusable. However‚ there is no consistency in the results
