Part A- Additive Volumes First‚ obtain a dry 10 mL volumetric flask that includes a stopper with it and weight on a digital scale. Be sure to get the mass at the closest milligram. Then‚ pour DI water to the calibration mark of the flask. Place the stopper back and weigh it again on the same digital scale. Once recorded‚ it is okay to pour this water down the drain. Observations: Mass of Empty Flask Mass of DI Water Filled Flask 15.114 g 25.048 g Now‚ put 100 mL of ethanol in a beaker and

The average contents (±SD) of kaurenoic acid in the Araliae Continentalis Radix extract powder were estimated as 1.147±0.008 mg in 1.0054 g‚ usual dose of Araliae Continentalis Radix. Quantification of kaurenoic acid UPLC–MS/MS has been emerging as a powerful analytical technique for the determination of analyte in biological samples to improve sensitivity and selectivity. Herein‚ we developed a simple‚ selective‚ and sensitive bioanalytical UPLC-MS/MS method for the quantification of kaurenoic

Experiment 20: pH Titration: Phosphoric Acid in Cola Drinks Post-lab Assignment or Report The post-lab report for this experiment is due at the beginning of the following lab period. Student notes for the lab will be available on the lab T-Square site. Learning Objectives Students will be able to... • Use a known mass of solid acid to determine an unknown concentration of a basic solution (this process is called “standardization”). • Execute a titration using good‚ reliable technique.

The Equilibrium Constant of an Ester Hydrolysis Reaction Jesus Flores March 30th‚ 2015 Abstract: This experiment was conducted in order to discover the Kc‚ equilibrium constant‚ of a hydrolysis reaction of an unknown ester #2‚ unknown acid‚ and alcohol #2 products. The first week consisted of creating the reaction mixtures in bottles‚ next was preparing a NaOH solution while neutralizing with KHP. The final week consisted of titrating the bottles with the NaOH solution prepared previously

Aspirin were used to relieve pain‚ inflammation‚ and fever. Aspirin were made using a combination of salicylic acid and acetic anhydride.The goal of this experiment was to determined the purity of aspirin using different methods. These methods included‚ reacting salicylic acid with FeCl3‚ finding its melting points‚ and by doing Thin-layer chromatography. When you reacted salicylic acid with FeCl3‚ changes in color will occur. Pure Aspirin has a melting point around 135°C and a pure salicylic acid

A. The scientific principle behind step A is all to do with burning the seaweed and turning into ash. To do this it had to be done with a Bunsen burner which was on the blue flame so it was at its hottest to turn the seaweed into ash. B. In step B the scientific principle is the filtration of the purified water. The reason for the ash being boiled was to extract the iodine ions. D. The scientific principles behind step D was the adding of hydrogen peroxide solution to the remaining
Premium Chemistry Solvent Ethanol
Purpose This experiment shows how different concentrations of acids and bases in a solution affect its pH level. When acids and bases are combined in a solution‚ they neutralize each other. This means that depending on the concentration of both acids and bases in a solution‚ the pH will vary. A neutral pH level is 7; anything below that level is known as an acidic solution‚ while anything above is known as a basic solution. To find out the pH‚ the solutions will be diluted and tested with different

Discussion: Extraction and crystallization- The purpose of this lab was to extract and crystallize compounds in a mixture using acids and bases. 1 gram of the unknown was dissolved into 30 mL of ethyl acetate. The mixture was then transferred to a separatory funnel. Using aqueous solutions of different pH we were able to separate organic acids‚ bases and neutral compounds from each other. Using three 10 mL portions of HCl‚ we reacted the HCl with the base in solution. This made it possible to
