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

Brandon Schmetterer 3-13-15 Biology labs DNA Extraction Lab DNA is extracted from humans for genetic testing‚ for body identification‚ and for analysis of forensic evidence. The first step of DNA extraction is to take cheek cells from the test subject. Next‚ the cells must be burst open in order to release DNA. Third‚ DNA is separated from protein and debris. Lastly‚ the DNA must be isolated. A buccal swab is necessary in order to collect the cheek cells .The micropipettes are used to add lysis
