Recommended: Composition of magnesium oxide

The composition of water in magnesium sulphate pentahydrate using measured values is 46.0% water and 54.0% magnesium sulphate. The composition using defined values is 51.12% water and 48.83% magnesium sulphate. The hypothesis for the value of x was 6, and the experiment conducted also resulted in the value of 6 for the number of water moles to magnesium sulphate. However, the hydrated salt has 7 moles of water to 1 mole of magnesium sulphate, creating magnesium sulphate heptahydrate. This shows that there were experimental errors when conducting the experiment. One of the possible reasons why the calculations resulted in a different number was due to the hygroscopic nature of magnesium sulphate. As it is hygroscopic, the ionic compound continuously

    The unknown bacterium that was handed out by the professor labeled “E19” was an irregular and raised shaped bacteria with a smooth texture and it had a white creamy color. The slant growth pattern was filiform and there was a turbid growth in the broth. After all the tests were complete and the results were compared the unknown bacterium was defined as Shigella sonnei. The results that narrowed it down the most were the gram stain, the lactose fermentation test, the citrate utilization test and the indole test. The results for each of the tests performed are listed in Table 1.1 below.

    Triphenylmethyl Bromide. A 400 mL beaker was filled with hot water from the tap. Acetic acid (4 mL) and solid triphenylmethanol (0.199 g, 0.764 mmol) were added to a reaction tube, with 33% hydrobromic acid solution (0.6 mL) being added dropwise via syringe. The compound in the tube then took on a light yellow color. The tube was then placed in the beaker and heated for 5 minutes. After the allotted time, the tube was removed from the hot water bath and allowed to cool to room temperature. In the meantime, an ice bath was made utilizing the 600 mL plastic beaker, which the tube was then placed in for 10 minutes. The compound was then vacuum filtered with the crystals rinsed with water and a small amount of hexane. The crude product was then weighed and recrystallized with hexane to form fine white crystals, which was triphenylmethyl bromide (0.105 g, 0.325 mmol, 42.5%). A Beilstein test was conducted, and the crystals produced a green to greenish-blue flame.

    First, the freezing point depression of magnesium chloride was found. To begin, an ice bath was created in a 600 mL beaker filled with ice provided in the laboratory and rock salt. Next, Four different solutions with concentrations of 0.0 g (control), 0.2 g, 0.4 g, and 0.6g of magnesium chloride and 15 mL of deionized water were created. Each solution was made in a 100 mL beaker. The solutions containing magnesium chloride were stirred with a glass rod until the salt was completely dissolved. All equipment was cleaned with deionized water to minimize cross contamination. To calculate the freezing point, a Vernier temperature probe provided in the laboratory was used. The temperature probe was plugged into the GoLink!

  • Alkaline Phosphatase Lab Report

    1662 Words  | 4 Pages

    Alkaline Phosphatase (APase) is an important enzyme in pre-diagnostic treatments making it an intensely studied enzyme. In order to fully understand the biochemical properties of enzymes, a kinetic explanation is essential. The kinetic assessment allows for a mechanism on how the enzyme functions. The experiment performed outlines the kinetic assessment for the purification of APase, which was purified in latter experiments through the lysis of E.coli’s bacterial cell wall. This kinetic experiment exploits the catalytic process of APase; APase catalyzes a hydrolysis reaction to produce an inorganic phosphate and alcohol via an intermediate complex.1 Using the Michaelis-Menton model for kinetic characteristics, the kinetic values of APase were found by evaluating the enzymatic rate using a paranitrophenyl phosphate (PNPP) substrate. This model uses an equation to describe enzymatic rates, by relating the

    A precipitation reaction can occur when two ionic compounds react and produce an insoluble solid. A precipitate is the result of this reaction. This experiment demonstrates how different compounds, react with each other; specifically relating to the solubility of the compounds involved. The independent variable, will be the changing of the various chemical solutions that were mixed in order to produce different results. Conversely the dependent variable will be the result of the independent variable, these include the precipitates formed, and the changes that can be observed after the experiment has been conducted. The controlled variable will be the measurement of ten droplets per test tube.

    In this lab, a metathesis reaction between an unknown metal carbonate (M2CO3) and calcium chloride (CaCl2), dependent on the ionic states of both compounds, allowed for identification of the metal through gravimetric analysis. Two grams of the metal carbonate were measured using an analytical balance and then dissolved in an aqueous solution with CaCl2 such that CaCo3 and a metal chloride formed from the reaction. The total mass of the metal carbonate was 112 grams per mole. Subtraction of the mass of CO3 from the total mass informed the metal’s identity: sodium. Due to the loss of precipitate and the utilization of two pieces of filter paper, a wide margin of error exists.

    Metabolism is defined as the chemical processes that take place within an organism, such as production of energy (Nature Education, 2014). One component of metabolism occurs through gas exchange. In animals, gas exchange occurs through a process called diffusion where materials move from levels of high concentration to low concentration (Freeman, 2013). It usually occurs in the respiratory system of animals, the lungs, where oxygen is inhaled and carbon dioxide is exhaled (Freeman, 2013). However, some animals may also exchange gases through other unique methods. For example, Rana pipiens, or leopard frogs, have vascularized skin that are extensively essential in their extremely wet habitat (Hoese and Abraham, 2014).
