Acid-base chemistry can be used to separate the components of a mixture, if one or more of those components are acidic or basic, based on the solubility of that mixture. Solubility is the ability of a solute to dissolve in a solvent and it’ll usually form a solution. An extraction is when compounds are dissolved from a solid into a solvent or from a solution into another solvent. Solvent-solvent is when nonaqueous solvents and reagents are used to remove an element from an aqueous solution. The…

Likewise, if the DCM was to be extracted with HCl, the sodium acetylsalicylate will not form and therefore the DCM layer will have contents of sodium acetylsalicylate which means that the inclusive percentage of Aspirin and the overall percentage of the unknown substance would be moderately superior. Sodium bicarbonate will remain in an alkaline state which means the acidic properties will be also be removed and therefore the extraction of sodium bicarbonate will be fairly weak during the…

I. INTRODUCTION Did you know that yeast is the only substance that is asleep until you mix it with something in order to activate it? Well, many people may say, “No.” Well if we thought about it, what activates bread to rise? From experience as a young family baker, when yeast is added to the bread, you need to mix warm water and sugar. These ingredients once mixed together, create a reaction with each other because sugar is the key that helps expel the carbon dioxide that's needed. The purpose…

Smoothie Separation Lab Report 1) Our final smoothie product was not separated. We accomplished this by the addition of the Milk Juice smoothie stabilizer at around 3/4 of a teaspoon. We added that to about 2/3 of a cup of water that we were heating up on the stove and stirred until the stabilizer dissolved. Once it dissolved we removed the pot from the stove and put into the freezer to cool. While the water mixture was cooling, we made a simple syrup. Our simple syrup was made with roughly…

The “Acid Bath Murderer” case was about a man named John George Haigh. It was said that he killed his boss and dumped him into a forty-gallon barrel of acid (Casale,2017). Like most known killers, Haigh blended well into society. Born into a strictly religious family on July 24, 1909, Haigh claimed his childhood to be strict and somewhat lonely. During his youth, Haigh had an accident which resulted in having a blue bruise on his head. His mother told him that this blemish was a result of his…

Graph 4 demonstrates the correlation between the transmittance and concentration levels of KMnO4, in how as the levels of concentration increase, the transmittance decreases. The experiment during week 2 was very similar to week 1 except we used potassium phosphate instead of potassium permanganate. Table 3 demonstrates the effect of wavelength on T% and absorbance. The same equation used for Table 2 was used in Table 3 in order, to calculate the absorbance. The highest absorbance level was…

Comparing the Absorptivity of Two Sequestration Agents Macy Freireich* & Alekhya Geddan ABSTRACT In this experiment it was decided which sequestration agent, charcoal or magnetic bentonite clay, was more effective at absorbing the PAH model, Procion Red MX-5B. By way of spectrophotometry, the collected absorptivity and concentration values of each of the diluted samples of the Porcion Red MX-5B were graphed and evaluated in comparison to the measured absorptivity of the dye extracted from…

Table 1, shows the exact chemicals used to prepare silica solution, zinc acetate solution and zinc nitrate solution. For the zinc acetate, adding 2-propanol to the hydrated zinc acetate will result in a white solution with some precipitations of zinc acetate in the bottom of the beaker, then by adding 2.1 grams of diethanolamine, ratio is 1:1, the solution will be transparent; due to the effect of diethanolamine which increases the pH of the solution, make it basic. Dissolving zinc nitrate in…

Materials and Procedure The materials that were used were the following: 4.268 grams of zinc sulfate heptahydrate, 2.586 grams of calcium acetate monohydrate, Analytical balance, 220 milliliters of deionized water, stir stick, two 100 milliliter glass beakers, one 250 milliliter glass beaker, filter paper, ring stand, glass funnel, and an Erlenmeyer flask. All of the materials listed above were obtained or taken into consideration before experimentation began. A piece of weight paper was…

DEVIATION BACKGROUND: On 07/28/2017, During the inspection of PRODUCT A on TP- 18, while the operator was transferring the coated tablets into a plastic scoop, which is used to load the coated tablets into the printer product hopper during the printing, what appeared to be a live and small gnat fly was observed inside the product bag. This was discovered after the operator pulled the product liner off the coated drum to pour the remaining tablets into the scoop. Per routine procedure, during…
