48% yield). The crude acetaminophen was then recrystallized in a solvent of water and methanol over heat resulting in 0.082 grams (39.61% yield) of pure acetaminophen. Melting points of both crude and pure acetaminophen were taken‚ and found to be 165.9 - 170.9°C and 168.2 - 171.5°C‚ respectively. The literature melting point of acetaminophen is 169.5 – 171.0°C‚ indicating that our final product was pure. Introduction The synthesis of acetaminophen involves the attraction

In its forms lies the essence of purity‚ as it continuously morphes creating new ones. While taking a first look at Socrates’ mind and work‚ we see a fundamental core of his theories is the concept of Absolute Purity. Socrates speculates on the theory of Pure and True knowledge; specifically‚ the Eidos of an idea regardless of time or people. In his quest to eradicate the world of mystery‚ he creates a systematic way‚ an algorithm of sort‚ to reflect the purity of justice in all of our acts through

Freezing and Melting of Water. 10/24 Richard Landolfi Due Date:11/1 Purpose the purpose of this lab is to determine the freezing and melting temperature of water. Freezing temperature‚ the temperature at which a substance turns from a liquid to a solid‚ and melting temperature‚ the temperature at which a substance turns from a solid to a liquid. Hypothesis If the water is at a low temperature then it will freeze

Properties of Two Types of Solids SCH3U0 Maggie Liu Abstract The purpose of this lab is to study some of the physical properties of two types of solids – ionic and molecular. The samples used are sodium chloride (ionic) and camphor (molecular). The physical properties studied are odour‚ hardness‚ melting point‚ solubility in water and solubility in 2-propanol. It is observed that some of the physical properties of sodium chloride are no odours‚ hard‚ a high melting point‚ soluble in water and

The Isolation‚ purification and identification of Proteins assayed From Bovine Liver Using SDS Gel Electrophoresis‚ Mass Spectroscopy and Western Blotting Abstract The purpose of the experiment was to isolate and recognize varying protein solubilization and assaying methods by using bovine liver protein. The experiment implicated the impact of different types of solvents like ethanol‚ water‚ PBS‚ PBS+1% Triton x-100‚ and PBS+2% SDS on protein solubilization. Bradford and Ghosh/Dumbroff

Liquids and Solids Chemistry 1211 Fall 2012 Section 1: Abstract‚ Experiment and Observation Abstract: The purpose of this experiment is to determine the boiling point of a liquid and the melting point of a solid. We also were able to observe the difference between boiling and melting point Experiment and Observation: We used isopropyl alcohol and set up an experiment to observe the boiling point. We set up a second experiment using acetamide to determine the melting point

Class 4 – Flammable Solids Division 4.1 – Flammable Solids are: • Wetted explosives that are Class 1 explosives when dry‚ that are sufficiently wetted to suppress explosive properties. • Self-reactive materials that are thermally unstable and can undergo strong exothermic decomposition even in the absence of oxygen. Readily combustible solids that can cause fire through friction‚ such as matches. Powdered‚ granular or pasty materials must be classified as Division 4.1 when the time of burning of

AMERICAN INTERCONTINENTAL UNIVERSITY SUBJECT: Municipal Solid Waste Descriptions and Problems ABSTRACT: The Municipal Solid Waste is based in 4 main components that are recycling‚ composting‚ landfilling and waste-to-energy that is mainly done by burning the waste. This is known as materials of no longer being of value and is thrown out for disposal. Waste is handled and separated into different containers which are divided into solids‚ plastics and paper mainly. There are different types of
