How did the amount of Sodium Citrate‚ an anticoagulant‚ added to a Calcium Chloride solution affect the volume of the clots formed when a sodium alginate solution‚ a blood simulation‚ was introduced? Mackenzie Keesor (Fall Semester 2017-2018) Purpose The purpose of this experiment was to observe the differences in the formation of simulated blood clots when different amounts of sodium citrate‚ an anticoagulant‚ was added to the coagulation process‚ which would help gain information about the process

Purpose The purpose of this experiment is to determine the mass of sulfate in the precipitate from the reaction of BaCl2 (aq) + SO42-(aq) → BaSO4(s) + 2Cl-(aq) while utilizing gravimetric analysis methods. Introduction Gravimetric Analysis utilizes the mass of a product to calculate the quantity of the original unknown analyte‚ Quantitative Chemical Analysis page 674. While this method of chemical analysis has been established since the eighteenth century‚ it

about determining the quantitative amount of sulphate inside barium sulphate‚ BaSO₄‚ using the method of gravimetric analysis. This quantitative determination is done by the addition of a dilute solution of barium chloride slowly to a hot unknown sulfate solution slightly acidified by concentrated hydrochloric acid‚ HCl. The white precipitate of barium sulphate is filtered off‚ washed with water‚ oven-dried‚ and weighed as barium sulphate. The quantitative amount of sulphate is deduced from mathematical

2. An aqueous solution of KCl is colorless‚ KMnO4 is purple‚ and K2Cr2O7 is orange. What color would you expect of an aqueous solution of Na2Cr2O7? Explain. Orange. 3. Explain why hexane will dissolve benzene but will not dissolve sodium chloride. Sodium chloride is an ionic compound. 4. Some drinks like tea are consumed hot or cold‚ whereas others like Coca-Cola are consumed only cold. Why? For taste reasons‚ these drinks can be drunk if the user likes It but having coca cola like tea

The mean data observed show a number of trends. The average weight and length tend to decrease as the amount of Ammonium Sulfate approaches the full recommended dose. On the other hand‚ the average amount of protein per gram of tissue tends to increase as the amount of Ammonium Sulfate approaches the full recommended dose. Our null hypothesis was that there is no difference between the mean weights or the mean lengths of the seedlings two different treatments. (A+B‚ A+C‚ and B+C) Each of these

Sodium‚ one of many elements in the periodic table is being used in everyday life‚ it is also an essential element within your body. It is just another element‚ but one of the differences is that this element is something that most people consume every day. Sodium has played an important role in everyday life because of its uses in medicine‚ industry‚ and agriculture(Shriver). Sodium was discovered in 1807 by a man named Sir Humphrey Davy. He was well known for his discoveries of most alkali metals

(objective/subjective) would you expect to find? What test(s) are done to help provide a definitive diagnosis? o Well to begin with‚ I would want to ask the patient to rate his/her pain. For an acute episode‚ the best medication to treat with is analgesia. Morphine sulfate is given to relieve pain and reduce ureteral spasm (LeMone‚ 2015‚ P.758). o Other assessment data I would expect to find is complaints of flank‚ back‚ or abdominal pain.

In the experiment‚ we tested a sodium chloride solution. Along with the tested solution‚ control groups (water and sodium phosphate) were used to be help understand whether or not NaCl was a buffer. Water was the negative control group and sodium phosphate was the positive control group. If NaCl was a buffer than the pH would be stabled as the sodium phosphate buffer. If NaCl was not a buffer than the pH would fluctuate like the negative control‚ water. During the first trial and prior to the drops
