    to prepare stock solutions and determine specific gravity and density of sodium chloride of known concentrations. This lab required us to prepare a stock solution and use that stock solution for three dilutions. Each dilution had a different molarity because of the end volume. The first diluted solution had a concentration of 0.3107 M and a density of 1.0081 g/mL. Out of all the dilutions this was the lowest concentrations because it had to most water added to the stock solution. The second diluted

    spread from areas of high concentration, to areas of low concentration. Osmosis is the diffusion of water through a membrane, moving molecules from an area of high concentration, to an area of low concentration. The capability of an extracellular solution to move into or out of the cell is known as tonicity. Three terms are used when relating to tonicity; Hypertonic, Hypotonic, and Isotonic (khan, 2016). In hypertonic environments (where there are more solutes outside than inside the cell) cells will

  • Fluoride Argumentative Essay Solution

    1745 Words  | 7 Pages

    Fluoride. What is it? A nutrient? A medication? A pollutant? Water fluoridation has been a popular matter that has been going on for years. Many cities have been implementing fluoride in public water systems and many have not. The reason behind water fluoridation is that can help tooth decay. But fluoride’s adverse effects prevent some cities from imposing this practice. Water fluoridation should not be implemented within public water systems due to its detrimental effects on health, its catastrophic

    Developed by Steve de Shazer and Insoo Kim Berg, Solution-Focused Brief Therapy (SFBT), is a behavior based, goal oriented, treatment system that focuses on the present and future, rather than past experiences, to find solutions to problems (Goodtherapy.org, 2016). This paper will explore Solution-Focused Therapy, its core constructions, approach, and techniques. Core constructs Berg and de Shazer (as cited by Fiske, 1998), used three principles to direct their philosophy when creating SFBT: (1.)

    how a client would like their life to be, rather than focusing on the past and the origin of problems (Lutz, 2017, What is Solution-Focused Therapy section, para. 7). Mariah does wish to continue her education, as prior to her grandmother’s illness she was not struggling but rather excelling in her academics. Due to the circumstances, Mariah has found that a possible solution to her current stressors would be to obtain her GED while also spending as much time with her grandmother as she can. She has

  • Lab Report: Diffusion And Osmosis

    percent of sucrose solution out of the four variables; 0% , 5%, 10%, and 15%. After we filled the beaker we then got two potato cores. Once we had the cores we cut the skin off the ends. Following this we then cut the two potato cores into four 2.00 cm potato cores. After they were cut into 2.00 cm each we found the mass. We zeroed out the scale and weighed all four potato cores at once and recorded the mass. We then put those potato cores into the beaker of 75 mL of solution. With the potato cores

    standard solutions were prepared. As a whole, the experiment was conducted by four people, however, for Part A, the group was split in two to prepare the two different solutions. Calibrations curves were created for the standard solutions of both Red 40 and Blue 1. Each solution was treated with a serial 2-fold dilution to gain different concentrations of each solution. The serial 2-fold dilution were done with a volumetric pipette, its pump, and 10 mL volumetric flasks. Eight different solutions were

    3-4 days to dissolve its shells, which results in a delicate shell membrane connecting the inner contents of the egg. The shell is selectively absorbent only to water. The solution that is the dissolved in the internal contents of the egg is approximately 18-20% which is the solute concentration. solute concentration is the solution that will be dissolved by the egg. The process that will be tested for the egg is osmosis, which is the diffusion of water across a selectively permeable membrane from an

    to the investigation into the murder case. Data analysis revealed that Mr. Green had a specific reason for killing her. Further research revealed that Miss Scarlet had been poisoned by Mr. Green using a silver nitrate solution. It was found that Mr. Green’s silver nitrate solution had a molarity of 0.564 M using the balanced chemical equation. The conclusion that Mr. Green committed the murder and used silver nitrate as a murder weapon is supported by this evidence. This case is a reminder of the

    isolation of the desired product from the solution, will illustrate a typical application of extraction.  Some organic acids are liquid and are soluble in water as indicated. The sodium salts of these acids are ionic compounds that are also very soluble in water. If an aqueous solution of one such salt is acidified with a strong mineral acid, the much weaker organic acid is produced.  The weak organic acid is largely un-ionized in the aqueous solution.  No apparent change is observed when the

    Determining Tonicity of Solutions as Compared to Decalcified Eggs   Abstract: Osmosis is the tendency of molecules of a solvent to pass through a semipermeable membrane, from an area of higher concentration to that of a lower concentration. The following experiment was designed to utilize this principle in order to determine the tonicity of a set group of solutions, as they related to eggs. In this experiment, decalcified eggs were placed into four different solutions, with mass measurements of

    Qualitative Data: It was evident that after the potato cylinders were taken out from the sodium chloride solution after an hour, the ones that gained mass had increased in rigidity, becoming more turgid as well as appearing bigger than before. Their color also changed from distinct yellow to a lighter shade of yellow. On the other hand, potato cylinders that were put in a high concentration solution shrunk in size and they became shorter in length since they lost water. They felt softer, more flexible

    fact that it has little to no sodium. This experiment is connecting to the pH scale because if I used water of a pH of 3 then for my next trial I use water of the pH 8 I would not have controlled data and to conclude there will not be any isotonic solution with a base percentage as a final answer. Therefore, we must use the same pH leveled water in order for the amount of salt to stay controlled throughout the whole
