Lab 5 Acid/Base Extractions Introduction The purpose of this experiment is to separate either the organic base (amine) or organic acid (carboxylic acid) from a mixture that contains inorganic impurities (salt) by performing a liquid-liquid extraction and then taking a melting point. Key Experimental Details and Observations Our starting material‚ Compound B‚ was a fine white powder and weighed 0.535g. The final product was a shiny white sheet that resembled acrylic paint and weighed 0.109g

First‚ solvents are used to mix together all the ingredients in a nail polish to yield a uniform liquid product. a. The type and amount of solvent determines how thick a polish is and how long it takes to dry b. Most Common solvent- ethyl acetate. c. Ill talk more about what the solvent does in a few slides. d. See pic 2. Another ingredient are resins- a polymer material that holds the polish

Extraction Separation of a Carboxylic Acid‚ a Phenol‚ and a Neutral Substance Purpose The objective of the experiment is to identify the three substances in the mixture and to determine the percent recovery of each from the mixture. The unknown will consist of either benzoic acid or 2-chlorobenzoic acid‚ 4-t-butyl phenol. Determine the weight of crystals and also the percent yield Introduction There are various techniques of extractions‚ solid/liquid extraction‚ which

The purpose of the first part of the experiment was to produce a chemical compound which was the alum crystals by using aluminum‚ potassium hydroxide and sulfuric acid. After the compound was present‚ the purpose of the second part of the experiment was to make sure that the compound that was formed in the first half of the experiment was actually alum. Some of the experimental techniques that were used in this experiment was filtration using the Büchner funnel vacuum filtration‚ recrystallization

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

Pre-Lab: Analgesic drugs are known for reducing pain‚ while antiseptic drugs reduce symptoms such as fevers and swelling. However‚ some of these drugs can reduce both illnesses. To obtain a pure compound in these drugs‚ the scientist needs to separate the desired compound by taking advantage of the different physical and chemical properties. Such as; different boiling points

extracting lipids or fats from foods‚ both the method as well as the solvents chosen to perform a complete‚ or close to complete extraction are important. If these two elements are not taken into consideration‚ the extraction may not be complete‚ or the extract may contain a large quantity of undesired impurities. The natural fats and oil are mixtures of glycerides of fatty acids. Fats and oils are naturally occurring organic compounds which belong to a large group of water insoluble substances called
