Introduction Sope Creek is located in Marietta, GA, and is the test site of recent water quality index tests. It contains multiple rapids that are rated up to Class III. However, Sope Creek is rather shallow, with an average depth of only about two feet. (U.S. Geological Survey, 2011) Our test site was about the same, at a depth of one foot. The water quality index is made up of multiple tests that include the following: pH, Turbidity, Temperature, Dissolved Oxygen, Nitrates, Phosphates, Total Solids, Fecal Coliform Bacteria, and Biological Oxygen Demand.
However majority of the solid Iodine was left at the bottom of the test tube; which leads to the conclusion that it’s not reactive on water. 2. Solid iodine in 1 mL of potassium iodide is slightly more soluble. The liquid in the small test tube turned a dark brown color. 3.
Save and submit your completed Lab Report to the appropriate weekly Dropbox. Taking Screenshots The instructions below provide basic guidance on taking screenshots of your labs 1. Complete the lab step that you would like to capture in a screenshot. 2. Make sure that the window you want to capture is in the foreground.
The moisture in the zone is called groundwater; it seeps slowly through the ground following the pull of gravity and guided by rocks structure. The saturated zone is referred to as the water table. The orientation and slope of the water table usually conform roughly to the slope of the land surface above, nearly always approaching closer to the surface in valley bottoms and being more distant from it beneath a ridge or hill. Where the water table intersects Earth’s surface, water flows out. A well dug into the zone of saturation fills with water up to the level of the water table.
Oil hypothesis accept/reject = Accept, the final result had very little oil in it. b. Vinegar hypothesis accept/reject = Accept, the final result had very little vinegar in it. c. Laundry detergent hypothesis accept/reject = Accept, the final result had a great amount of laundry detergent in it. 3. What affects did each of the contaminants have on the water in the experiment?
Calculations Write out all steps of the calculations that you conducted in order to solve for the formula of the hydrate. Organization and sub-titles are important for this section of the lab report, as are units and formulas on all data used in the calculations. For example, you can use subheadings such as “Subtraction to determine the initial mass of the hydrate” to explain what is being done in each calculation and why. Discussion and Conclusion: The first part of this section of the lab is the discussion, in which you discuss any mistakes that may have been made (or what measures were taken to try to avoid mistakes) and what improvements, if any, you can think of for the procedure for the next time the lab will be conducted. In the discussion section of this lab report, you will want to discuss the importance for heating the hydrate for a sufficient amount of time.
Heterogeneous mixtures have varying composition throughout the mixture. Muddy water and rocks are examples of heterogeneous mixtures. Chemical and physical properties are used to separate these mixtures. Solubility is an example of a physical property used to separate mixtures. When water is added to a mixture of salt and sand, the salt dissolves, but the sand does not.
Qualitative Anion Tests Peter Jeschofnig, Ph.D. Version 42-0192-00-01 Lab Report Assistant This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor. Observations Data Table: Qualitative Anion Tests | Name | Test Tube 1w/HCl | Test Tube 2 w/AgNO3 | w/HNO | Test Tube 3Confirmation | Bromide | NR | Brownish/gold | Not dissolved | Not dissolved | Carbonate | Gas | White | Not dissolved | Dissolved with NH4OH | Chloride | NR | Milky yellow | Not dissolved | Purplish color | Iodine | NR | Yellowish | Dissolved | Yellowish | Phosphate | NR | NR | NR | Not dissolve | Sulfate | NR | Brownish milky | Not dissolved | Gas/ no result with silver nitrate | Sulfide | GAS AND ODOR | NR | No dissolve | Not dissolve/odor rotton egg.
Explain how you determined this. a. Pyrite hypothesis accept/reject = Rejected The hypothesis was rejected as the pH levels in the water increased when tested. While it was only one level, it was higher than the original sample. b. Coal hypothesis accept/reject = Rejected The hypothesis was rejected as the pH levels in the water increased when tested.
