Buchner funnel 8. Spatula 9. Weighing machine Method 1. Weighing paper was used to weigh approximately 1.00g of ‘impure Benzoic acid to produce re crystallization’. 2. Moved it to a 125ml Erlenmeyer flask. 3. Poured approximately 20ml of distilled water by using a graduated cylinder

was heated while water was added through the funnel being careful to keep the volume in 500 ml distillation flask. The glassware was covered with foil to ensure proper heating. When the mixture started to boil the temperature was recorded. After the mixture was heated‚ the distillate product was obtained and the spent cloves and water were disposed. Extraction of Eugenol A mixture of 25 ml distillate and 10 ml CH2Cl2 was placed into a separatory funnel. This mixture was extracted and 15 ml of extract

Introduction Friedel-Crafts acylation of anisole with acetic anhydride was used in this experiement to synthesize 4-methoxyacetophenone with the use of a reflux apparatus. Friedel-Crafts reactions can be done by alkylation‚ which involves mixing an alkyl or acyl halide with a Lewis acid‚ or acylation‚ which is done with acid chlorides or anhydrides(Lefevre). Acylation was used because it does not have as many disadvantages aklyations reactions have such as polyalkylation‚ second electrophilic attacks

24grams of unknown sample and 0.12 grams benzoic acid was weighted and placed in a test tube. 2. 10ml of ether was added to the mixture and was shakes to dissolve completely the mixture. 3. The solution then transferred to 125 ml separatory funnel and 5ml of 1M NaOH was added‚ with the cap tight‚ the layers was mix by swirling and shaking for 30 seconds. Pressure was vent by titling

Method Take a 250cm3 beaker and fill it with distilled water. Use distilled water so there are no impurities to disrupt photosynthesis. Then take x cm’s of elodia and put it in the beaker. Cover the elodia with the large end of a funnel and the tip of the funnel cover with a test tube. Then direct a light onto this experiment. Measure the amount of bubbles that come from the elodia for x minutes. A prediction for this experiment would be that as different wavelengths are tested the rate of

Various types of tornadoes include the land spout ‚ multiple vortex tornado‚ and waterspout. Waterspouts are characterized by a spiraling funnel-shaped wind current‚ connecting to a large cumulus or cumulonimbus cloud. They are generally classified as non-super cellular tornadoes that develop over bodies of water‚ but there is disagreement over whether to classify them as true tornadoes. These

Background Information: Yeast is a fungal microorganism that is used to manufacture mainly bread and beer. It reproduces rapidly. Fermentation is the process by which yeast takes in sugar and releases alcohol and carbon

Experiment #1: Separation of Acid‚ Base‚ and Neutral Compounds from a Solid Mixture by Liquid-Liquid Extraction Introduction Liquid-liquid extraction is a technique used to separate chemical substances in order to purify or identify the various components of a mixture. Flavors‚ spices‚ perfumes‚ and medicines are just some of the everyday things that are extracted from plants and other natural sources [1]. The basic principle used to carry out this separation is the mixing of two liquids that are

Usually an aqueous and organic phase are used. During extraction the desired compound moves one phase and leaves the unwanted substance behind. Extraction normally has to be done a few times to leave all of the impurities
