Chemical tests

A. There a many different test that are chemical and physical that we could use for our soil sample. One physical test that can be performed is a particle size distribution of a soil sample. For this test, you get your sample of soil and place it in a jar. You then add water, a drop of soap, and shake the jar. After a length of time the contents of soil will develop into layers. You would then see the makeup of your soil with sand being at the bottom, silt in the middle, and clay at the top. You

substance is unclassified, many tests are required to be done to determine the substance. Performed in Avila University’s Chemistry Laboratory, five chemical reactions between a group of chemical standards where used for observation. These reactions and standards where then used to determine an unknown substance. To determine the unknown substance, a total of six close examinations where done to make sure the unknown substance, accurately matched one of the chemical reactions. Procedure To perform

Laboratory Report Title: Identifying the four major classes of macromolecules through various tests. Group Members: Antonia Johnson, Payton Ewing, Lenneisha Hepburn, Kendisha Hanna,   Introduction:  Macromolecules also known as biological molecules are monomers which are the simple units of polymers. All macromolecules contain carbon and hydrogen which are found in organic compounds. In this Experiment we will test for the presence of protein, starch, lipids, and sugars by analyzing the content off food

ask you to submit to two different types of tests. The first of which is known as a breathalyzer or DUI breath test and the second of which are called chemical tests. Even if you fail one or more of these tests and get subsequnelty arrested for a DUI charge, its important to note that depndng on the type of test that you failed, a legal representative can challenge both types of tests in a variety of ways. This is due to the fact that neeither types of tests are 100% accurate. To put things in retrospect

contends that that the result of the breath tests should not be relied upon since Officer.....that performed the tests was not able to recall the Title 17 of the California Code of Regulations. Therefore, he was not qualified to operate the device followed the correct protocol to perform the test. » Determination: Counsels contention is considered, however, Title 17of the California Code of Regulations is not only limited to the chemical breath test. Per Title 17 of the California Code of Regulations

1.4 Physical Tests 1.4.1 Organoleptic Tests This will be used to determine the color, odor, and physical appearance of the extracted substance. 1.4.2 Solubility Tests Six hundred milligrams of fucoidan isolate will be weighed and divided into 6 tubes, 100 mg each. It will then be dissolved in 1mL of each individual solvent such as distilled water, ethyl alcohol, chloroform, 1M Hydrochloric acid, 1M Sodium Hydroxide, and Diethyl ether. 1.5 Chemical Tests The chemical tests that will be performed

Observed reactions and recorded in the table below. Cleaned out the 5 test tubes. Data: Iodine Test Results Discussion: The iodine test was successful. Potato juice and starch were the only two substances containing starch. Again, glucose and onion juice contains glucose, while water doesn't contain starch or glucose and was just tested to make sure the test was done properly. SUDAN III TEST Introduction: Sudan III test detects the hydrocarbon groups that are remaining in the molecule. Due

Identifying Organic Compounds Joe Harris 11/12/07 1. Background Organic compounds are, by definition, any chemical compound containing carbon. These compounds include carbohydrates, polysaccharides, lipids, proteins, and nucleic acids. Each one of these compounds has a different purpose. Carbohydrates give energy to cells when consumed. Lipids are basically the

Biological Molecules Experiment-Specific Questions Experiment 1: Monosaccharide Test 1. Fill in the table below with the results from the monosaccharide test experiment, and your conclusions based on those results. Results Monosaccharide Test Solution Initial Color Color with Benedict's Solution Color After Heating Monosaccharide? glucose solution      clear   blue   orange   yes water      clear   blue   blue no   sucrose solution      clear   blue

which could potentially create a The colour of the precipitate that forms a purple precipitate (J.M Bailey,W.J Whelan, 1960). The colour happens because of the iodine reacting with the glucose inside the starch. (J.M Bailey,W.J Whelan, 1960). Biuret test is to detect protein is extremely small, it is supposedly around the value of 0.5mg/ml. (Crowe,2014). This means 0.5>x M of protein, the biuret solution would not change the if any solutions consisted less than the face value will not be detected 0
