Isolation and Identification of Eugenol: The Fragrant Component of Cloves *Adri‚ Kiersten Jayne R.‚ Aguinaldo‚ Samuel Jr. Group 2 Department of Chemistry‚ College of Science University of Santo Tomas‚ España‚ Manila 1008 Abstract. In this experiment‚ the primary objective was to isolate eugenol from cloves. An amount of 30 grams of dried cloves and 300 mL of water was distilled over a flame for over 2 hours. The distillate underwent extraction with dichloromethane‚ water and sodium hydroxide

05.05 Mixtures and Solutions Background: Paper chromatography is one method for testing the purity of compounds and identifying substances. Paper chromatography is a useful technique because it is relatively quick and requires small quantities of material. Safety: Warnings: * Rubbing alcohol (or isopropyl alcohol) is flammable‚ so be sure to keep it away from high heat or heat sources. * Keep pigments and solutions away from your eyes‚ wash your hands carefully after coming in contact

09/18/2012 09/19/2012 Title: Separation of Mixtures and Solids Purpose: The purpose of this experiment was to practice the process of separating mixtures of different solids. Procedure: This experiment consisted of different processes to separate a mixture of solids into the four individual solids: sand‚ benzoic acid‚ iron fillings‚ and sodium chloride. To remove the iron fillings from the mixture I used a magnet and scanned it across the entire mixture and the magnet forced picked up all the

NANCY MARASHI. | Background: During this experiment students will take a mixture and separate it into its’ pure substances. A mixture is a combination of two or more substance. These substances cannot be combined chemically but more physically. The pure substances are substances that cannot be separated any more by physical means. The students

SPECTROPHOTOMETRIC DETERMINATION OF EQUILIBRIUM CONSTANT OF A REACTION UNIVERSITY OF THE PHILIPPINES‚ DILIMAN QUEZON CITY‚ PHILIPPINES August 2‚ 2013 ABSTRACT The objective of this experiment is to determine the equilibrium constant‚ denoted Keq‚ for the formation of [Fe(SCN)]2+ complex which is a product of the reaction between the ions Fe3+ and SCN-. In performing this experiment‚ solutions containing FeCl3 and KSCN‚ diluted in HCl‚ were measured for their absorbance using a UV-Vis

Introduction Atoms‚ molecules‚ compounds and mixtures‚ although they may not seem it‚ are different. Atoms make up all of the above and elements. They are made an equal amount of protons and electrons. Molecules are made when two or more atoms connect chemically. Like molecules‚ compounds are made when two or more atoms connect chemically. Unlike molecules‚ the atoms need to be two or more different elements. Mixtures are made of two or more compounds or elements. Mixtures can look completely the same when
