EXTRACTION OF BENZOIC ACID‚ 2-NAPHTHOL‚ AND NAPHTHALENE FROM UNKNOWN SAMPLE # 131 Douglas G. Balmer (T.A. Mike Hall) Dr. Dailey Submitted 11 July 2007 Introduction: The purpose of this experiment was to separate a sample of benzoic acid‚ 2- naphthol‚ and naphthalene of unknown proportions using a two-base extraction method. The three components of the mixture will react differently to sodium bicarbonate and sodium hydroxide because each of the bases’ conjugate acids has a different pKa. The

This paper is an analysis conducted on Nucleic Acids through a variety of tests specifically‚ Dische‚ Murexide‚ Wheeler-Johnson and Phosphate Tests in order to exemplify structural features of nucleic acids as well as identify the principle involved in each chemical test. Different procedures and different test compounds were applied‚ and results were noted as for changes in colors of precipitates or solutions. For Dische Test‚ light blue was obtained for RNA and dark violet for DNA. For Murexide

Abstract The aim of this experiment was to determine which of the samples of vinegar if any had been watered down‚ to complete this task a sample of commercial vinegar was tested twice using titration and an average was taken of the two samples to give a base line to compare the potentially tampered samples against. Introduction Vinegar is a solution made from the fermentation of ethanol (CH3CH2OH)‚ which in turn was previously fermented from sugar. The fermentation of ethanol results in the production
