Acetic anhydride

there were two very strong acids, one of them didn’t show any visible reaction which is #65, so it was 1 M nitric acid, which means #60 was 1 M hydrochloric acid. #61 was a strong acid that didn’t react with any of the other solutions, so it was 3 M acetic acid; which means #68 was 0.1 M aluminum nitrate. #62 was a weak acid that did react with NaOH forming brown precipitate, so it was 0.1 M silver nitrate. Both of #63 and #69 are weak acids, but, #63 did react with 0.1 M silver nitrate, so it…

vinegar, bromothymol, sodium hydroxide and Lugol was shared throughout the classroom by other classmates. Before the labs began, we initiated by labeling the two trays. The four-well tray reagent tray was labeled with tea, starch, MOM and 0.1 M Acetic Acid. The three-well reagent tray was labeled in number from one to three. We then dedicated a pipet for each tray as well as distributing other liquids to other trays. The first lab focused on changing the concentration of Hydrogen ions…

Title: Methylcobaloxime: A Model for Vitamin B12 Aim: To create methyl(pyridine)cobaloxime(III) as a model for methylCobalamin, the methylated form of vitamin B12, Introduction: Using Co(I)Cl2 as a starting material, it is possible to produce a cyano(pyridine)cobaloxime like compound, Chloro(pyridine)cobaloxime whose chemistry can be investigated via means of methylation, as such using the Chloro(pyridine)cobaloxime as a model for replicating chemistry already known of…

All American EFX Kre-Alkalyn (pH-Correct Creatine) This is the brand that started is all on June 4th, 2002 when Kre-Alkalyn® was awarded United States manufacturing patent #6,399,661. Kre-Alkalyn® EFX is "buffered" creatine that does not convert into creatinine prior to reaching skeletal muscle tissue. It is packaged in a purple capsule that can be administered orally. Kre-Alkalyn® EFX is manufactured exclusively by All American Pharmaceutical Corporation. Why a critical adjustment to…

In the biomolecule lab, we conducted the lipid chromatography experiment to separate a mixture of biomolecules from lipids. If a positive test is conducted by the end of the experiment, there should be smudges aligned vertically on the chromatography paper, or silica gel strip, indicating the separation of different lipid molecules that were present in the substance. In contrast, if a negative test is conducted there would be no smudges aligned vertically on the chromatography paper. Substances…

Introduction: The purpose of the experiment was to determine the density of powdered grape. The company Gatorade has advertised that G2 powder replenishes fluids and electrolytes in the body’s blood stream during exercise. G2 has aided in staying hydrated, “maintain normal muscle performance, heart rate and brain activity” (1). In relation, there has been a rise in sports drink purchase to improve athletic performance. The experiment examined a basic level of G2 powders composition, the…

Scientists use a scale to measure how acidic or basic a liquid is. That scale is called a pH scale. The pH scale is a number from zero to fourteen. Accordingly, zero to seven liquids are considered acid. However, seven is considered a neutral, like distilled water. Therefore, eight to fourteen the liquids are considered basic. For instance, a pH of two is going to be an acidic liquid. Thus, a pH of twelve would be measured as a basic liquid. Additionally, a strip of litmus paper will…

The steps of synthesis process can be explained in Fig. 1. The Zn (NO3)2.4H2O (zinc nitrate tetrahydrate) and Al (NO3)2.9H2O (aluminum nitrate nonahydrate) (Merck) are used as a precursor. ZnO precursor solution with the concentration of 0.15 M was made by dissolving 0.89 grams of powder precursor Zn(NO3)3.4H2O in 40 ml of solvent. Solvent comprises a mixture of 30 ml deionized water and 10 ml of ethanol. To speed up the process of dissolution, the mixture was stirred using a magnetic stirrer…

The purpose of this experiment was to determine the identity of nine solutions using the results of reacting pairs of solutions in an organized systematic manner. Known solutions were used on the first day. The second day, the solutions were placed in code-labeled bottles. The reactions from the previous day were then used to help identify which solutions were which, by closely monitoring which unknown solutions mixed with other unknowns and how they reacted, such as: color changes,…

Process To Make Copper Coated / Plated Nails 1) Measure out 1/4 cup white vinegar and put into the glass bowl. 2) Add 1 teaspoon salt. Stir salt until it dissolves in the vinegar. 3) Take a penny and submerge it into the vinegar solution 1/2 way for 10 seconds. 4) Remove penny. What do you notice? What do you think happened? 5) Put all the pennies into the bowl and let them sit in the white vinegar solution for 5-10 minutes (take notice of how the pennies look before putting them in). 6) Take…
