...Lab #1 “Who has the same solid that I have?” Abstract Different Physical and chemical tests were performed on 10 numbered unknown solids and the results of all tests were compared as a class to try and determine which groups had the same unknown solids based on similarities in properties. It was found that my given unknown solid #11 shared similar properties with the unknown solid #1. A side by side analysis of the reactivity test in which Hydrochloric acid (HCI), lead nitrate (Pb(NO3)2) and sodium hydroxide (NaOH) was added to three separate samples of the compounds unknown #1 and #11 aqueous solutions. The results for both unknowns were identical, leading to the conclusion that my unknown solid #11 was the same unknown solid as #1. Introduction When conducting research it is important to be comfortable communicating your results with other researchers so that they can be further analyzed and compared with the results of other research experiments. Another large part of conducting research is to be comfortable determining, describing and comparing chemical and physical properties of compounds. Many compounds can look very similar, but have drastically different chemical properties, so it is important to know which tests can be performed on a compound to help determine what it is, or what it is not. In this experiment 2 sets of six unknown solid compounds were put into small jars and labeled with the numbers 1-12, numbers 4, 6 and 8 were not used. Each lab group was......

Enzyme Lab Report

...The purpose of the enzyme lab conducted was to observe the chemical composition of cells. In order to do so we tested for the presence of organic molecules. Molecules are what forms when atoms bond together. Organic molecules of cells include proteins, carbohydrates, and lipids, which are composed of smaller molecules known as monomers and polymers. Polymers are joined monomers. A chemical reaction links monomers together occurs and releases a water molecule, this is called dehydration synthesis. Hydrolysis separates polymers into monomers by using water to break bonds. Organic catalysts called enzymes are proteins that increase the speed of a chemical reaction. In the lab we used Biuret reagent to test for proteins, iodine solution to test for starch, paper to test for lipids. In the first lab, we tested for the presence of proteins in samples by using blue solution called Biuret reagent, which changes to purple when a protein is present and pinkish-purple for peptides. First test tubes were marked at 1cm and then filled to the mark with water, albumin, pepsin, and starch. Next, five drops of Biuret reagent was added to the sample, covered with Parafilm, and swirled to mix. The water remained clear, indicating the sample lacked the presence of proteins, and thus was our negative control. The albumin sample observed changed to an orange-purple color, indicating the presence of protein. The peptin sample changed to a pink-purple hue, testing positive for presence of......

The Freundlich Isotherm q=αC1v was then found to be a better model to approximate the adsorption isotherm for BSA as compared to Langmuir Isotherm. From the experimental data, the static capacity determined from Langmuir Isotherm approximation was estimated to be 330.033mg/g and the dynamic capacities flow rates of 5.0, 2.5, 0.5 ml/min were 0.918, 1.431 and 2.066 mg/g respectively, thus agreeing with theoretical knowledge that the static capacities should be larger than dynamic capacities as sufficient time were allowed for......

Lab Report

...Milovanovic Mr. Brian Gorodetsky Science 9 November 20th 2013 LAB Density Guiding Question: How does sugar/salt affect the density of water? Hypothesis: I think that the density will increase because salt and sugar add mass to the water, therefore increasing the density. For example, ocean water, it is more dense than the regular water because it isn’t pure like regular water, it has more salinity in it making it more dense. Notes: -A sugar and salt experiment. -We did 5 tests for each. -First, we calculate the density of PURE water, then with adding gram-by-gram of sugar or salt. -We used 10ml of water in each test. -Density=mass/volume, in this case mass/10ml Tables: Salt: Sugar: Graphs: Salt: Sugar: Calculations: Conclusion: From the graphs, tables and calculations it is shown that the solution between sugar and water is denser than the solution between salt and water. This is because sugar is sweet and when it is in contact with water it turns into a honey-like structure. Also, when salt is in contact with water, it’s formula, NaCl, splits up leaving each element with a charge and making more space for more salt, therefore leaving the solution less dense, where sugar doesn’t split up, it stays together making the solution denser. Evaluation: The mistakes we made at the beginning were that we didn’t put the EXACT amount of the solvent (water) and the solute (salt/sugar), but then we realized that some of......

...Final Lab Report (Water Quality and Contamination) Student’s Name Course Name Institution Instructors Name Date of Submission Final Lab Report Abstract Establishing water quality was done by analyzing the chemical, physical and biological characteristics. This process helped determine safe water for human consumption in public in addition to making sure that humans are not affected by chemicals or disease causing organisms. This was done by analyzing 3 water samples which entailed Tap water, Fiji® bottled water and Dasani® bottled water. The goal of this research was to establish the effects of ground water contamination. This research necessitated hypothesizing on the capability of oil, vinegar and laundry detergent to pollute ground water in view of soil as a contributing filter of oil. Arising from the results obtained from the data analysis and observations from the experiments, conclusive evidence about bottled water was deduced and further research consideration is brought to light. Introduction Water quality was established by analyzing various characteristics which entail chemical, physical and biological. There are benchmarks of water quality set for every of these classes of characteristics. The benchmarks for water quality are advanced by (EPA) Environmental Protection Agency (2004) and (WHO) World Health Organization (2011). The quality of water taken in public was determined in the view of these benchmarks. Water quality research is significant due......

Final Lab Report

...Final Lab Report James Dillon SCI 207: Dependence of Man on the Environment Instructor: Jessica Bostock February 20, 2016 Final Lab Report Abstract The experiments conducted for this lab report focused on water contamination and filtration. Experiment 1 was effects of groundwater contamination. Oil, vinegar, and laundry detergent were added to clean water with no means of filtration. The clean water was found to be contaminated. A filtration system consisting of cheesecloth and 60 ml of soil was created and the contaminated samples were filtered through it. The soil and cheese cloth did not affectively filter the contaminants. Experiment 2 focused on water treatment and a filtration system using cheesecloth, sand, activated charcoal, alum, and gravel was created. The contaminated water sample was created by mixing soil and water together. After the contaminated water was put through the filtration system and a few drops of bleach were added you could see that much of the sediment was filtered out, but an overwhelming bleach smell remained. The third experiment was to determine drinking water quality. Samples of Dasani and Fiji bottled water were compared to my local tap water. Test strips were used to determine each samples ammonia, chloride, alkalinity, chlorine, hardness, phosphate, and iron levels. The results were that the Dasani water was cleaner overall and that the Fiji water......
