Sodium Chloride Reaction Lab Report

664 Words3 Pages

The purpose of this experiment was to observe and conclude the impact of a higher alkalinity and increasing sodium chloride concentration had on the yield of lysozyme crystals through crystallization. The constants for this process were sodium acetate at a concertation 0.05 M for every well in both rows, along with the concentration of polyethylene glycol (PEG) being set at 10% for every well in both rows. The two rows of wells that were tested deviated in alkalinity, row A having a pH of 4.5 and row B having a pH of 4.8, along with the sodium chloride concentration of each well. The concentration was increased by 0.5 M each well following the control well of 0.0 M sodium chloride. As seen in Figures 1-4, (blocks A1, A1*, and B1*,), no crystals formed when sodium chloride was not present. Figure 4 (block 1) you see what could possibly be some crystal formation, but this was determined to only be an obstruction, possibly dust, on the coverslip. Crystals were …show more content…

As seen in Figures 1 and 3 (blocks A2* and B2*) the higher yield of crystals formed were found in the higher alkalinity solution of row B. This confirms the first part of the hypothesis, that an increased alkalinity generates a greater yield of crystals. The second part of the hypothesis was concluded from looking at Figures 1 and 3 that as the salt concentration increased in each well, the yield of crystals increased. Combining both parts of the hypothesis into one and comparing the number of crystals formed in each row, row B with the greater alkalinity and with increasing sodium chloride concentration had the greatest yield of crystals. This greater yield can be contributed to the increase sodium chloride concentration and increased alkalinity, which disrupts the repulsion between lysozyme crystals during

    In this lab we were trying to figure out if Salt Creek and Barker Lake had the correct chemical balances to sustain catfish for the years coming. In order to find this out, we tested the water using a Hach Water Testing Kit. Inside were dissolved oxygen reagent powder pillows 1, 2 and 3 which we added and mixed into our sample water to prepare it for testing. Then we added droplets of Sodium Thiosulphate Solution into the prepared water too see how much dissolved oxygen parts per million were in the water. Our independent variable in this experiment was the 5 different testing sites that we went to for water samples.

    The purpose of this report is determine if sodium chloride is a viable option as a deicer on winter roads. To determine this, one must compare a multitude of factors. In this lab, the freezing point depression of water, enthalpy of dissolution, cost, and environmental impact will be discussed. A large factor in how effective a substance is as a deicer is it’s ability to decrease the freezing point of water. If the freezing point of water can be lowered, the outside temperature must be much colder to reach this new freezing point, resulting in less ice on the roads.

    The lab started off by measuring critical materials for the lab: the mass of an an empty 100 mL beaker, mass of beaker and copper chloride together(52.30 g), and the mass of three iron nails(2.73 g). The goal of this experiment is to determine the number of moles of copper and iron that would be produced in the reaction of iron and copper(II) chloride, the ratio of moles of iron to moles of copper, and the percent yield of copper produced. 2.00 grams of copper(II) chloride was added in the beaker to mix with 15 mL of distilled water. Then, three dry nails are placed in the copper(II) chloride solution for approximately 25 minutes. The three nails have to be scraped clean by sandpaper to make the surface of the nail shiny; if the nails are not clean, then some unknown substances might accidentally mix into the reaction and cause variations of the result.

    The column was gently tapped to remove air pockets after adding the sand and alumina. The chromatic column was pre-wetted with CH2Cl2 (about 3 mL) until it began to drip. About 1 mL of the unknown was added to the column and the level of the solution in the column was allowed to descend to the top of the alumina. It was made sure that the solvent level did not drop below the alumina layer. Once the level of the sample reached the top of the alumina, CH2Cl2 was carefully added to the column without disturbing the sand or alumina.

    Explain why the reaction between sodium sulphate and silver nitrate did not occur even though sodium sulphate is insoluble in the most part? The reaction did not occur because the solution was mixed with 0.1M of silver nitrate and 0.1M of silver nitrate is not strong enough for the reaction to occur. If silver nitrate contained more than 0.1 mole, the reaction would have occurred because silver sulphate is insoluble and is a solid. Why is it needed for barium nitrate and ammonium sulphate to dissolve into water separately first before mixing the two together?

    Part A When sodium was added to water, the sodium melted to form a ball that moved around on the surface of water rapidly and hydrogen gas was produced. Because of the amount of heat liberated during this exothermic reaction, the hydrogen gas ignited the sodium with an orange flame while floating on the water. Also, when potassium was put onto the water, the observation was similar to how sodium reacted towards water. The metal was also set on fire, with sparks and a lilac flame. But, in the case of speed of tarnishing between the two elements, potassium was faster than sodium.

CaCO3, commonly referred to as limestone, is an organic substance and is, in a sense, the crystallised “carbonic salt” of the element, calcium2. In addition to being a salt, the pH level of Calcium Carbonate is 9.91, and it is therefore, a basic substance, due to the fact that it is comprised of a pH level higher than 7, which is neutral3. HCl, however, is the bodily acid found in the stomach of human beings.

    Bio Chem lab Report 04 Enzyme Biochemistry Group Member: Chan Man Jeun Duncan (16002621) Law Sze Man (16000478) Introduction Enzyme is a protein base structure substance in our body. It works at a biocatalyst that will catalyzing the chemical reaction, which helps to speed up the chemical reaction. Enzyme could only function in specific shape, and the shape of enzyme is depending on the environment, therefore it is hard for an enzyme to function well in an extreme environment. The aim of this experiment is to see can the enzyme functions normally in different environment(pH, temperature and salt concentration) via using starch solution, amylase from saliva, 0.5M HCl solution, 0.5M NaOH solution and NaCl solution, and using iodine solution

    The MG state is a compact denatured state with a significant native like secondary structure but a largely disordered tertiary structure. In addition, there are studies demonstrating that proteins can convert from unfolded to folded or molten-globule states upon addition of large amounts of crowding agents. For instance, unfolded cytochrome c at pH 2 can adopt a molten globule structure in the presence of crowding agents, unfolded RNase A at pH 3 adopts a folded-like structure upon addition of 350 mg/ml PEG 20,000 or Ficoll 70, and the reduced and carboxyamidated form of RNase T1 that is intrinsically unstructured at pH 7 was found to exhibit some catalytical activity upon the addition of 400 mg/ml dextran 70. In addition, protein binding to a membrane surface results in “partial denaturation” (i.e. being transformed into a non-native state). The effects of various polyols, such as ethylene glycol, glycerol, erythritol, xylitol, sorbitol, and inositol, on the structure of acid-unfolded horse cytochrome c at pH 2 were investigated.
