Tessa Landauer Chemistry 0340 Qualitative Analysis Shaopeng Zhang January 26‚ 2015 I submit this laboratory report as an original document. I assert that all ideas and discussion of data contained herein is my own work unless otherwise referenced. Tessa Landauer Abstract The goal of the experiment was to isolate and purify the unknown D liquid and solid by using its acidic and basic characteristics in a chemically active extraction then to identify the unknowns by analyzing the physical properties

Formal Lab Report | Chemistry | | Student name: Sara Hattar Grade: 10 ”C” | | Teacher: Christine Ziadat | | | Title: Investigating the effects of changing the concentration of an acid on the rate of reaction between HCl and Magnesium. Aim: In this experiment we are going to see the effects of using three different concentrations of HCl when added to Magnesium metal on the rate of reaction. Hypothesis: If the concentration of the acid increased in reaction between HCl (the acid)

Abstract By working with physical isopods‚ ordinarily known as pill bugs‚ sow bugs or roly- polies‚ we tried whether these sowbugs favored a dark spot to a light place. Included in the lab are a few outlines and tables sketching out our aftereffects of the test. We measured recurrence

The Determination of the Concentration of Hard Water Ions by the Titration of EDTA By Hannah Denby Lab partners: Heidi Kiziah‚ Leonie Hamel University of Central Florida‚ CHM 2046L December 3rd‚ 2015 Abstract. The “hardness” of water is a common dilemma attributed by high concentrations of metals such as calcium and magnesium. This is a result of the properties of water; because it is a good solvent‚ impurities are easily dissolved. As water moves through soil and rock‚ it dissolves minute amounts

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
