Download file to see previous pages This reaction is as below in a simplified form by abbreviating the crystal violets chemical formula as CV.
The violet-colored CV+ reactant slowly faded to a colorless product as the reaction proceeded, following the typical behavior of any indicator. The colour change were be measured by a Vernier Colorimeter set at 565 nm of wavelength in assumption that absorbance is directly proportional to the concentration of crystal violet according to Beer’s law.
The molar concentration of the sodium hydroxide, NaOH, solution was much greater than that of crystal violet. This ensured that the reaction, which is first order with respect to crystal violet, was first order overall throughout the practical experiment. The reactions were monitored at different temperatures, while maintaining the initial concentrations of the reactants the same for each of the trial. The effects of temperature change on the rate of reaction were observed and measured. Finally, the activation energy, Ea, for the reaction was calculated.
In this lab Experiment the apparatus and materials used included Lab Quest , Lab Quest App Temperature Probe, Vernier Colorimeter, Temperature Probe, 5 plastic cuvettes, 0.10 M sodium hydroxide, NaOH, solution, 2.5 × 10–5 M crystal violet solution, 1 liter beaker, ice, watch with a second hand, two 10 mL graduated cylinders, two 100 mL beakers and 50 mL beaker.
In this experiment, the procedure was as follow. The initial step involved obtaining and wearing goggles. This was followed by connecting the Colorimeter to Channel 1 of LabQuest and the Temperature Probe to Channel 2 of LabQuest and choosing New from the File menu.
The next step involved changing the data-collection rate to 1 samples /second and the length to 200 seconds. The colorimeter was the calibrated and the calibration used for all the four trials in the done in the experiment. In calibrating the colorimeter, a blank was prepared by filling an ...Download file to see next pagesRead More

Pathways of NOS Activation

...? ‘Your Human Anatomy 3 Dec Pathways of NOS activation Outline Nitrous Oxide Synthase system and activation pathways for iNOS and eNOS The nitric oxide synthases (NOS) were first identified and described in 1989, with at least three major isoforms identified (Alderton). Since then, there has been an explosive quantity of research on the enzyme, with its knowledge database growing day by day. NOS are dimeric enzymes that catalyse the chemical reaction using the substrates l-arginine, NADPH, and oxygen to give the products of nitric oxide (NO), citrulline and NADP. They are associated with various cofactors, including tetrahydrobiopterin, FAD, FMN and iron protoporphyrin IX. Although there has been some...

Activation of inflammasome

...that directly triggers inflammasomes activation, and as such they were useful in this assay. In order to characterize diverse circumstances under which inflammasomes could be stimulated. In the case of ataxia telangiectasia mutants, interleukin 1-beta could still be secreted even in the absence of the normal energy currency ATP. The lack of a negative regulator is responsible for a cascade of inappropriate immune reactions forming one of the principal manifestations of the disorder, which was also demonstrated in figure 3, which provided evidence of impairments in interleukin and caspase processing in ATM -/- mutants. The condition itself does not appear susceptible to an obvious treatment modality based...

Embryo Gene Activation

...Embryo Gene Activation Embryonic stem cells are valuable and special, which are isolated from early embryonic stages and forms the system for the development of the embryo. Embryo gene activation is the process in which an embryo starts transcription of the new genome. For synthesis of proteins and cleavage, embryo gene activation is of great importance as it aids in those processes. The period in which embryos take to break and start the embryonic gene activation is different and depends on the species of the animal (Haian 15). Embryonic genes, which are active prior to the 4-cell stage, are small in number and they code for proteins used in controlling...

Crystal Lake Manufacturing A NAFTA Dilemma

...Crystal Lake Manufacturing - A NAFTA Dilemma Brooms have existed for centuries to sweep and clean gardens and houses but the broom as we know it today, was invented in 1797 by Levi Dickenson. He then developed a machine in order to consolidate the broom he produced: the broom machine was invented in 1810. Shortly after that, in the mid-1820s the Shakers who were a religious order changed the design of Dickenson's broom and turned it into the flat broom that we know today. In the 19th century the U.S. broom industry was so developed that it started to export brooms all around the World. The west conquest even helped in finding new places to grow broom corn as it appeared to be very fertile. This finally led to the...

The Crystal Cathedral

...of mosques and public baths. This specific mosque, being much different and refined from all those buildings, set an example for other Islamic buildings to follow. The crystal cathedral too has been an exception from the identified styles of Christian religious buildings. The building complex is unique in architectural history of Christian buildings and something that none of the other mega church had done before. The designs of the building are influenced by the society that produced it. The mosque has been covered from all the four sides with high walls to prevent any viewing from the surrounding, whereas the cathedral design facilitates the viewers from the outside to view the activities taking place...
