Abstract: This experimentation was to evaluate absorbance and the reaction rate of an enzyme‚ ’-amylase in starch-iodine solution. We will be testing the relationship between enzymatic reaction affected by temperature and pH. Through the testing the enzyme at different temperatures‚ and different pH levels; it would determine at which temperature and pH level the enzyme worked the most efficiently. Analyzing absorbance of the solutions with spectrophotometery will determine the reaction rate. To

Measurement of Iron in Foods by Atomic Absorption Spectrometry Chem 462 Abstract The purpose of this experiment is to find the amount of Fe in dietary tablets by UV-visible spectrophotometer. A Perkin-Elmer Lambda 6 UV-Visible spectrophotometer will be used for the unknown sample and the iron(II) standards. Introduction Fe3+ in a dietary tablet is converted to Fe2+ and reacats with 1‚10-phenathronile to form the tris(1‚10-phenanthroline) iron (III) complex. Hydroquinone is used as the

tested the effect temperature has on the rate of enzyme activity. The way we figured this out was by taking four different temperatures and testing the different absorbance levels they produced every 20 seconds for two minutes straight using a spectrophotometer. The important part of this experiment was the temperature the enzyme concentration was made at. What we got from the experiment was at lower temperature we got very low numbers for the absorbance‚ which gave us a lower rate for the enzyme

and Hydrogen Peroxide were added into the experimental tubes. The order in which you add these solutions is very important. The Hydrogen Peroxide must be added last and guaiacol should be added one tube at a time. When ready to put into the spectrophotometer the blank tubes should be put in first to blank the machine for a more accurate absorbance reading when the experimental tubes are put in. The absorbances for the experimental tubes were recorded every fifteen seconds for two minutes. This process

Introduction: This investigation used spectroscopy to evaluate light absorption in different solutions. A spectrophotometer was used in the lab to determine these values. A spectrophotometer is an apparatus used to “measure the absorption of radiation in the visible and UV regions of the spectrum and allows precise at a particular wave length” (Jones et al.‚ 2007). The amount of light absorbed by a substance is directly in relation to the concentration of the solute and also the wavelength moving

out with 1.93x10^15 using electrochemical cell method and 9.79x10^12 using spectrophotometer method. Considering the literature value of Kf is around 4.8x10^12 ~ 1.7x10^13‚ spectrophotometer gives more accurate result than electrochemical cell method. Formation constant of complex ion can be derived easily by Nernst equation in electrochemical cell method‚ but mass action expression with K4‚ Ksp‚ and Kb in spectrophotometer method generates more accurate and closer to literature value with less percentage
