Calibration

The purpose of the experiment was about recrystallization of crude ASA from crude ASA, then analyze the yield and melting point of Recrystallized product, test for Purity of Recrystallized ASA by using thin layer chromatography and analysis of Recrystallized Acetylsalicylic Acid by Spectroscopy to compare these results with another experiment about creating an Aspirin from Salicylic Acid. In this experiment, 0.1241 gram of Recrystallized ASA was produced from 1.1754 gram of Crude ASA and the…

its absorbance is calculated; you can accurately measure it by means of a standard graph called a calibration curve. Also colorimetry, a technique “used to determine the concentration of colored compounds in solution” (Housecroft, Catherine) is also an objective that was designed to be introduced. Lastly, determine the concentration of a solution with a previously unknown concentration using a calibration curve and plot it with different standard solutions. In order to accomplish this, the…

The overall objective of the experiment was to find the concentration of phosphate by using spectroscopy. Dilutions of a phosphate working solution with a known concentration were made and their absorption lengths were found using the spectrometer in order to find the concentration of the unknown phosphate sample. INTRODUCTION The goal of the experiment was to find the concentration of an unknown water sample using several standard phosphate solutions’ absorbencies and Beer’s Law. Knowing the…

same unique identifying quality, color, that cranberry juice has. In the experiment, a calibration curve, or standard curve to which an unknown can be compared, was…

it should be non-contact sensor as there should be no chance of contamination that may occur as a result of contact. Labatt prefers a sensor which is low maintenance, this would mean, being mounted for ease of replacements, services and minimal calibration necessary. Additionally, the temperature should be cost effective for the company, while…

because natural vanillin is costly. Before a chemical experiment or process is carried out, the concentration of an unknown solution will always be determined. After this step is done, a calibration curve will be drawn. The unknown concentration of the solution can be determined from the linear equation of the calibration curve where Beer’s Law is applied. To prepare a standard solution, there is specific technique that can be used. This…

(Trochim & Donnelly, 2008; Cozby & Bates, 2012). In the above example, a study of calibration activities at WGU might yield internal validity; however, applying this methodology outside of the unique job functions of faculty at WGU would prove difficult and external validity would be difficult to demonstrate, if not impossible. To demonstrate generalizability, the study would have to yield the same increased calibration results when applied to populations outside of WGU. An example of external…

Several accusations were made that manufacturers were incorrectly labeling the iron content on their products. The purpose of this experiment was to analyze the amount of iron in approximately one serving of Total Whole Grain cereal and in one iron tablet and determine if these accusations were true. The values collected would then be compared to the actual values for these products. Total cereal contains 100% of the recommended daily allowance for iron, and the iron tablet contains 361% of the…
