Title : The Vitamin C content of fruit juice Aim : To investigate the vitamin C content of fruit juice. Introduction : [2]Vitamin C‚ also known as the ascorbic acid or the L-ascorbate‚ is required for the growth and repair of tissues in all parts of our body. It is necessary to form collagen‚ an important protein used to make skin‚ scar tissue‚ tendons‚ ligaments‚ and blood vessels. Vitamin C is essential for the healing of wounds as well as for the repair and maintenance of cartilage‚ bones

While conducting my graduate research‚ I worked on different biophysical techniques such as gel electrophoresis‚ colorimetry and UV Spectroscopy. The applicability of instruments‚ such as high speed and ultra-speed centrifuge‚ one-dimensional and two-dimensional electrophoresis‚ Quebec Colony Counter‚ and quantitative PCR had been a significant part of my research during

This is the story of a man who lived a good life and contributed to the field of physics. He became personal friends with one of the smartest men in history‚ Albert Einstein. But as I said before‚ this is not the story of Einstein; it is about a man who helped create many breakthroughs which are still being learned about today in our schools. This is about Erwin Schrödinger‚ the guy with a cat in a box. Erwin Schrodinger was born on August 12th‚ 1887 in Vienna to a linoleum business owner. He was

The Spectrophotometric Determination of an Equilibrium Constant. Abstract: The report presents determination of equilibrium constant for the formation of a complex ion FeSCN2+. This was accomplished using a colorimeter to measure absorbance of some known concentration solutions in order to generate the calibration curve. The equation of the graph was used to compute the equilibrium concentrations of the reactants and products‚ needed to calculate the equilibrium constant for

Laboratory 4: Analysis of Color in Foods 1. Introduction: The purpose of this experiment is to use various forms of color analysis to evaluate the quality of commercial food samples. Color and appearance of foods is an important criterion that consumers consider when buying foods and contributes to the overall quality of a product. One way to visually perceive color is through the Munsell system. This widely used visual color-ordering system sorts the visual system into three parts: hue

Lab Report 3: Combustion of Magnesium and Specific Heat of a Metal C4C Jeffrey Silvin Fall 2017 Major Kittle Chem 100 T1 Introduction The purpose of this lab was to determine an experimental value for the heat of formation of MgO with Hess’s Law and then use the result to find percent error. To do so‚ approximately 50 mL of 1.0 M HCl was added to a calorimeter. Initial temperature was measured and then 0.25 g of Mg was added. After the reaction is completed the maximum temperature was recorded.
