PSBPP103 Differential Gram’s staining EXPERIMENT NO. 1 AIM: THEORY: Page No: C1 Date: To Gram stain the given bacterial suspension and to differentiate between gram positive and gram negative organism. Visualization of microorganisms in the living state is very difficult‚ not just because they are minute‚ but because they are transparent and almost colorless when suspended in an aqueous medium. To study their properties and divide microorganisms into specific groups for diagnostic purposes

flow downstream into the rivers and lakes‚ resulting in exceedingly high barium levels in the water. This can cause high amounts of contamination in not only the lakes but drinking water reservoirs. Three separate trials were conducted using the colorimeter and a BariVer Barium Reagent Powder Pillow mixed with the water sample. The tests produced results of 2 mg/L‚ 1 mg/L‚ and 1 mg/L. It was decided that another test must be done to get the most precise results as possible‚ giving 1 mg/L. With three

Lab Report Introduction This lab has the following two concepts: synthesis of acetylsalicylic acid and analysis of acetylsalicylic acid. Synthesis is a purposeful execution of chemical reactions to obtain a product. This concept is used in the first part of the lab; when we have to produce crystals of aspirin. Analysis is the separation‚ identification‚ and quantification of the chemical components of natural and artificial materials. This concept is used throughout the lab when we are analyzing

These measurements help in the registration of the characteristic reflectance spectra and the detection of the chromatic alterations. Measuring devices‚ such as spectrophotometers and tristimulus colorimeters‚ provide a numeric expression of color that is based on mathematical conversions of tristimulus values. Also‚ measurement reproducibility is also greatly affected by surface uniformity‚ which is significant‚ as surfaces of wall paintings tend to

General Chemistry II Determining of the equilibrium constant for the formation of FeSCN2+ Introduction The objective of this experiment was to determine the equilibrium concentration and then determine Kc. A dilution calculation was formed to determine the concentration of SCN- and Fe(SCN)2+. Each cuvette was filled to the same volume and can be seen in table 1. Then the absorbances were recorded from each cuvette and can be seen in table 1. A Beer’s law plot was made from the data that was recorded
