The fifth titration, acid into buffer 4, had no great change, but the pH dropped slightly, but remained at around a pH of 4 for the rest of titration. The sixth and final titration, base into buffer 4, had a similar reaction to the previous titration except for the fact that the pH increased slightly at around 15 ml of base and remained the same pH for the rest of the titration. The herb powder was placed into a glass bottle. Ultrasound-assisted extraction was carried out in an ultrasonic cleaner RKH Bandelin sonorex, Germany. The extraction efficiency was evaluated according to the percent content of AL and IS contained in the dried roots of Inula racemosa and calculated.
Mitochondria Lab Report Words 3 Pages. During this experiment, mitochondria were isolated from Twelve samples containing various volumes of mitochondrial suspension, assay buffer, DCIP, sodium azide, and citric acid cycle intermediates were prepared to be read by a spectrophotometer. The inclusion of the dye DCIP allowed for the absorbance of the reactions between the mitochondrial suspension and the TCA cycle intermediates succinate, malonate, and oxalate to be measured, as DCIP turns from blue to colorless as the activity of succinate dehydrogenase increases.
Experimental Findings Increasing the number of mitochondria in the reaction did increase the reduction of DCIP relative to the amount of mitochondrial suspension present. Although the overall absorbance increases as more milliliters of mitochondrial suspension is added to a mixture of 0. Although this change is not large, it does demonstrate that the addition of TCA cycle intermediates has an impact on reaction rate. The decrease in the rate of reaction of the sample containing 0.

Glass Tube Experiment Words 6 Pages Two cotton balls of identical size were soaked in hydrochloric acid and ammonium hydroxide and were plugged simultaneously to the separate ends of the tube. Creatinine Test Lab Report Words 6 Pages Standard solution The standard solution was tested for its value and was used in the calculation of the patient's urea and creatinine value.
Coagulation Lab Report Words 8 Pages 3. Valbenazine, an analog to Tetrabenazine, is an emerging approach to the treatment of TD that is showing potential. Valbenazine is considered a purified parent drug of the positive alpha isomer of Tetrabenazine. One advantage of this emerging drug is the less adverse side effect profile, and the once-a-day administration, as compared to Tetrabenazine, which has a more adverse side effect profile and requires frequent intake due to its rapid metabolism Muller, Approval hurdles for Valbenazine. Sulphonation — The Process Most electrophilic substitution reactions are irreversible but sulfonation is an exception.
Treatment of benzene with "oleum" a solution of SO3 in concentrated sulfuric acid will give the sulfonic acid, the electrophilic species being sulfur trioxide which is Lewis acidic. Fig — 1 Sulphonation : Benzene equation The sulfonic acid can be converted back by treatment with hot aqueous acid. The reason for this reversibility is the fact that the Wheland intermediate is overall. The unknown ketone is from a homologous series of methyl ketones.

Thousands of people were killed instantly and more than 25, people have died of gas-related illnesses, several thousands more maimed for life since. Introduction 1. Isomers Lab Report Words 4 Pages. Describe each: Isotope — The term isotope is used to describe elements that contain the same amount of protons, but different amounts of neutrons.
Secondary Sources:Yahoo Answers. Reliability: In my data, you could see that the 5. The results of the phenol-sulfuric acid analysis conducted in this experiment suggest that the data acquired was relatively precise but inaccurate with respect to the given carbohydrate concentrations of the soda and Gatorade samples. Using a standard curve generated from a glucose solution with a known concentration, the carbohydrate concentration of the samples was determined in terms of glucose and a low coefficient of variation was calculated.
However, a high percent relative error was apparent in the analysis of both samples. This may have been due to the fact that the analysis was conducted assuming glucose was the carbohydrate of interest, while, in fact, a significant portion of the monosaccharides would have existed as fructose a. Also we can see that because the data was taken at a certain time the results will not work for all times of the day. The experiment can be improved by using more accurate measurement when it comes to time and the distance, however this would not affect the results significantly because they are already very precise.
These include the relatively small sample size, the single-session design, and the use of nonclinical samples. In addition, human error could have affected the reliability of using salivary cortisol assays to measure cortisol levels. If there was a more accurate way to measure cortisol levels without the intervention of human error, this study could have benefited from it. Looking at this value, and comparing the experimentally determined values, the values do not exactly match up, but are close together, as the values are only 0.
One reason why the values may not match up is because of the amount of liquid used. Sometimes, the value of water poured into the graduated cylinder may not be equal to specific volume which was to be used. In order to improve that, making the water volume more precise may allow for more accurate results. Secondly, the type of water used may of affected the value. The graph displays a negatively skewed trend, which suggests that the hypothesis was not supported.
Sulphuric Acid Experiment Words 4 Pages. The results do not support the hypothesis that a higher surface area to volume ratio would result in sulphuric acid being diffused into the agar cubes in the shortest amount of time. This is evident in the results as the exact opposite to what was predicted occurred. Instead of the smallest cube with the largest surface area to volume ratio of 1cm3 having the quickest diffusion rate, it conversely took the longest at 0. This directly refutes the hypothesis. There was also no consistent trend evident in the results. Between the two largest blocks of 2cm3 and 3cm3, there was only a 0.
