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
