denaturants act upon or denature protein differently. This was determined using the principle of viscometry. An Ostwald viscometer was used to measure the viscosity of the prepared native‚ blank‚ denatured native and blank with denaturant solutions. The time required for the said solutions to pass through the viscometer were recorded and their viscosities were then calculated using the data. Experimentally‚ urea was found to be the best out of the six denaturants that were used. Results and Discussion

PEP Process Module 1 19 Aug 1999 SRI Consulting Process Summary This Aspen Plus model simulates the production of acetic acid by low pressure methanol carbonylation in the presence of a heterogeneous rhodium (Rh) catalyst and the promoter methyl iodide. It is intended to resemble the Chiyoda/UOP Acetica™ process‚ a novel heterogeneous methanol process for the production of acetic acid. This technology is based on a heterogeneous Rh catalyst in which the active Rh complex is chemically immobilized

the higher the absorbance. This experiment incorporated Beer’s Law and is focused on determining the stress that various alcohols have on biological membranes. Using five solutions of differing alcohol concentration for each of the three alcohols; methanol‚ ethanol‚ and 1-propanol and a small slice of beet‚ the stirred solution was placed into a plastic cuvette and then into a spectrophotometer and the absorbance of alcohol solutions were determined in order to conclude which alcohol and concentration

INTRODUCTION In this lab‚ we will be measuring the viscosity of samples of polyvinyl alcohols in order to determine the molecular mass of their components. Polyvinyl alcohol is an example of a synthetic polymer‚ which is a macromolecule. The general chemical structure of such compounds are well-characterized‚ although variation in characteristics such as molar mass‚ chain length‚ and extent of branching are not obvious from merely looking at their molecular formula. There is also the complication

other two systems were immiscible can be made. Methanol was a polar molecule while pentane was nonpolar. This matches the hypothesis which states that like dissolves like‚ polar cannot mix with nonpolar. Ex. oil and water cannot mix because water is polar while oil is nonpolar. The third system allowed 3 substances to be ranked from least to a greater polar molecule. Water is more polar than pentane and pentane is less of a polar molecule than methanol when it comes to comparing the mixture of water/pentane

Light Transmission Through Liquids With Different Viscosities Introduction Aim This experiment investigates the effects of different liquid viscosities on light transmission. The results of this experiment could greatly benefit marine biologists or other marine scientists. This would help them figure out how their flashlights would work in different water conditions in the ocean. Background Research Spectrophotometers are devices that measure the amount of light absorbed by a certain liquid

The first was methanol and the second was an unknown liquid‚ which may have been methanol‚ ethanol‚ iso-propanol and hexane. Methanol is a clear‚ flammable and toxic liquid which is sometimes used as a vehicle fuel. Its accepted molecular weight value
