Exp. 2 Separation of Three Compounds by Extraction Introduction: The purpose of this experiment is do demonstrate the proper procedures of extraction and to develop a practical understanding of this method. In this experiment‚ extraction is used to separate a known acid‚ base‚ and neural compound from each other. The first two compounds undergo proton transfer reactions in the presence of acids or bases. Acids RCOOH‚ like benzoic acid‚ was deprotonated to form RCOO-. Bases RNH2‚ like ethyl 4-aminobenzoate

Strawberry DNA Extraction Donovan Roberts Mrs. Caudill Honors Biology 3/7/11 Introduction The structure of DNA is made of nitrogenous bases‚ phosphate groups‚ and sugars. These three parts of DNA form hydrogen bonds and create a right-handed double helix. The location of DNA in a eukaryotic cell is found within the nucleus‚ bound to proteins. DNA can be extracted from within the cell. They are several steps you must take to retrieve DNA from within the cell. When extracting DNA cells

Experiment 2: Acid- Base Extraction Separation of an Organic Acid‚ a Base and a Neutral Compound Introduction: The extraction technique is often used in the organic lab to separate organic compounds from mixtures. One type of an extraction technique is the acid-base extraction‚ which is used to separate organic compounds from a mixture based on their acid-base properties.1 There are certain principles that must be taken into account when choosing a solvent system to perform an extraction. The solvents should

DETERMINATION OF COPPER BY COMPLEXATION‚ SOLVENT-EXTRACTION AND SPECTROPHOTOMETRY ABSTRACT To determine the concentration of copper in an unknown solution by using copper complexation‚ solvent extraction and spectrophotometry. Standards are used to create a calibration curve and the unknown concentration of copper is then calculated by using the linear equation from the calibration curve. The concentration of copper in the unknown solution 201 was found to be 12.57± 0.25 μg/mL. INTRODUCTION Copper
