Magnesium hydroxide

In the foregoing paper, the author reported that ethyl ester of highly unsaturated fatty acid freshly obtained from cuttle fish oil showed quite the same good nutritive effect as oleic acid ester for rat, while the acid exposed to air was proved to be extremely toxic. Since it seems to be most plausible that the toxicity is concerned with the formation of peroxide by autoxidation of unsaturated fatty acid, the author determined the amount of peroxide. The result proved. this was just the case,…

Argument Driven Inquiry Design a Cold Pack / Hot Pack A chemical change is to alter the identity of a substance. Properties of these chemical changes include color change, gas formation, temperature change, precipitate formation, odor, and change in acidity. In the hot and cold pack experiment we found it to be a chemical reaction An exothermic reaction is when the substance releases heat energy. An endothermic reaction is when the substance absorbs heat energy. In our experiment we created a…

Using your tongs, hold a small piece of magnesium in the flame. Do not look directly into the flame during this reaction. (1a) Pb (NO3)2 is a colorless solution. K2CrO4 is a yellow colored solution. Both solutions seemed to be odorless. When the K2CrO4 was added to the test tube that had the Pb…

The experiment that I am doing is to see if the water temperature affects the reaction time of an Alka-Seltzer explosion. I believe that it will affect the time of how fast the CO2 builds up because the faster it builds up, the quicker the reaction and therefore the explosion comes faster. Alka-Seltzer is a drug that is used for heartburn and indigestion relief, along with many other things. When Alka-Seltzer was first introduced, it was advertised in comics in the newspaper in 1931. In 2006,…

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…

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…

synthesized luminol by reducing 5-nitro-2,3-dihyodropthlazine-1,4-dione, using sodium hydrosulfite (Na2S2O4) and 3M sodium hydroxide (NaOH). The amount of luminol collected was 0.2693 g with the percent yield of 161%. The product of the first reaction was then used to recreate the chemiluminescence experiment by mixing luminol, oxidizing agent (hydrogen peroxide), and base (any hydroxide base). This reaction emitted a blue light along with yielding phthalate salt. The experiment showed the…
