The unique composition and purity of as-deposited SnS2 thin films prepared with different precursor solution volumes from 5 ml to 25ml were determined by EDX analysis as shown in fig 5, which brought out the presence of Tin and Sulfur as elementary components. Two different peaks were observed in the spectrums from fig 5 relevant to the tin and sulfur. The EDX spectra show that the weight percentage for the film prepared at the precursor solution volume of 5 ml is 36.8% and 63.2%, which is…

relationship between the relative quantities of substances taking part in a reaction or forming a compound, typically a ratio of whole integers. In the lab that I did with my group we used stoichiometry to find out the decomposition of sodium biocarbonate. Sodium carbonate is just another name for baking soda, and that is what we used on our lab. Baking soda is also used in some food items, such as pancakes, waffles etc… When the baking soda is being heated the decompositon part occurrs and when…

Abstract: The purpose of this experiment was to prepare and standardize a sodium hydroxide solution as well as determine the molar concentration in as strong acid and the percent by mass of acetic acid in vinegar. We used volumetric analysis, also known as titration, in both experiments. The average molar concentration for NaOH was 0.2749 mol/L while the average molar concentration of the acid solution was .2493 mol/L.The average percent by mass of acetic acid in vinegar was found to be 12.3 %…

environment the student had, was water and sodium chloride. In this instance water was the model cell (what was in the dialysis tubing) and Sodium chloride was the surround environment (plastic cup). The initial weight of the model cell was 13.2g, but after sitting in the sodium chloride solution over night the cell lost water and only weighted 11.6g. Since the solution of the model cell- in this case water- left the cell and entered the surrounding Sodium Chloride it meant the cell had a…

The % relative standard deviation (% RSD) was found to be below 5 % for all the four analytes in system precision and below 6 % in method precision. The data as shown in Table 3.4.3.3.3 and 3.4.3.3.4. LOD values observed for Hydrazine carbamate and Hydrazone carbamate were 0.0018 µg per mL and 0.00092 µg per mL respectively. The LOD value observed for both 1-Hydroxy benzotriazole and 2R, 3S Chlorohydrine hydrochloride were 0.0019 µg per mL. The LOQ values observed for all four analytes were…

Part one Make a 3 list of chemical safety hazards? The three chemical safety hazards are: Poison Toxic Corrosive Reactive Environmental hazards 2. What is Amalgam? Amalgam is mixture of metals of mercury with another metal and other metal. Almost all metal can be an amalgam with a form of mercury. 3. If you had to train someone on how to separate the mercury from the amalgam, what training would they need? WHY? If I had to train someone on how to separate the mercury…

Effect of Organic Solvents on Particle Size When anti solvent was 0.4% (w/v) F68 aqueous solution, the effect of various good solvent was investigated. These organic solvents include ethanol, methanol, PEG 400, propylene glycol. The result as mention in Table 16 & Figure 27 showed that the particles prepared by methanol were the smallest (317 nm) among other organic solvents. Ethanol, PEG 400, and propylene glycol produced the particles having the mean particle size of 525nm, 1274nm, 864nm,…

purpose and objective of this experiment was to determine the percent by mass of acetic acid within a sample of vinegar using volumetric analysis with the titration technique. The theory is that if the volume and molar concentration of the standardized sodium hydroxide (NaOH) solution is known, then the percent by mass of the acetic acid (CH3COOH) in vinegar can be calculated after a titration.1 Within this experiment, a NaOH solution was standardized with a primary standard acid of potassium…
