solution was mixed added to 100 mL of ice water in a 250 mL flask. This flask was in an ice bath because low temperatures reduce solubility. The solution was added to a flask with a plastic pipette. The mixture was stirred at high speed. The mixture turned cloudy and white. The temperature was 3. The mixture was then poured through a Buchner funnel using vacuum filtration. The water and succinimide (the other product formed) collected in the flask below the funnel. This was the filtrate. BCHA stayed on

was assembled with a water-cooled condenser and a drying tube. Isopentyl alcohol‚ glacial acid sulfuric acid is added to a 25 milliliter round bottom flask and attached to the reflux apparatus. The mixture was boiled‚ the extracted first using water followed by aqueous sodium bicarbonate. The mixture was dried using anhydrous granular sodium sulfate. After dried‚ the sample was placed in a distillation apparatus and heated. This resulted in 1.8g of pure isopentyl acetate‚ a 44% yield. Introduction

The Deagle “Can you hand me that mixture?” asked Dr. Scooter‚ the scientist that will hopefully save wildlife as we know it. She and her Assistant ‚Dr. Skippy‚ are trying to create a mixture to save animals from bullets. So to keep this a secret she has a secret lab deep‚ right underground. She is testing it on two animals that people hunt all the time. The deer‚ and eagle.”Sure.” said Dr. Skippy. Dr. Scooter mixed the two mixtures and tested it on a little hamster. The hamster just died on the

separate it from the mixture. Once the molecule is ionized it will precipitate out of the ether solvent and dissolve into the aqueous layer. The aqueous layer can then be removed and the pure substance can be obtained through crystallization. In this week’s lab a mixture of carboxylic acid‚ phenol‚ and a neutral substance were separated from an ether solution. First‚ the carboxylic acid was ionized with a weak base and removed. A strong base was then applied to the mixture to allow the phenol to

In the software‚ the chromatogram was smoothed first column by 0.1 and second column by 1.0. For Blob detection function‚ the thresholds were set minimum area as 200‚ minimum volume as 15000 and minimum peak as 140.0 (relative reference). In the chromatogram‚ 6 corresponding peaks (A-F) were detected by the above mentioned algorithm

In step1‚ one set up x as a mass of NaHCO3 in the original mixture. Thus‚ equation that shows that the total mass of NaHCO3 and Na2CO3 is 2.00g. In the second step‚ by using gravimetric analysis‚ one converts x into the mass of Na2CO3 that has been produced from heated NaHCO3‚ and states that the total mass of

Biological chemistry 1B Experiment 1: Thin layer chromatography [TLC] Aim The aim of this experiment is to apply the technique of TLC to first separate out a mixture of coloured dyes and then to do the same for selected range of amino acids. Procedure 2 MMs of each different colour were collected into separate beakers. Approximately 5 drops of water is added to each of the beakers containing the MMs and the tablets were stirred until

2009 Experiment 6: Fractional Distillation. Separation of Petroleum Hydrocarbons Abstract: A mixture of cyclohexane and toluene were separate from one another by fractional distillation in order to measure the composition of each fraction and prepare the sample for gas chromatography. Introduction: Distillation has been used since antiquity to separate the components of mixtures. This method has been used to manufacture different organic chemicals but the most recent application is
