separating and identifying the components of Panacetin‚ which is a common medication that relieves pain. The label reveals that Panacetin is composed of sucrose (10%)‚ aspirin (40%)‚ and Tylenol (50%). Although this information is reported‚ the true composition of Panacetin is questionable. While sucrose and aspirin are present in Panacetin‚ Tylenol may be replaced by an unknown component (acetanilide or phenacetin). Separation of the components of a sample of Panacetin may prove valuable in identification

aspirin‚ sucrose‚ and drug preparation. The purpose of this experiment was to determine the unknown component of panacetin. Panacetin contains aspirin‚ sucrose‚ and an unknown component. Dichloromate reacts with Panacetin to produce the sucrose as an insoluble solid. Aspirin is removed from the solution by reacting with sodium bicarbonate. The aqueous layer reacts with hydrochloric acid‚ the unknown component can then be isolated by evaporating the solvent from the dichloromethane solution.

Constituent of “Panacetin” 9/15/2011 Purpose: The purpose of this experiment is to determine the unknown component of Panacetin. Theory: Panacetin is an analgesic (pain reducing) and antipyretic (fever reducing) drug that is sold in drug stores. However‚ there is a suspicion that this bottle may be counterfeit‚ not containing the chemicals that it should. Panacetin should be made up of about 50 percent of the unknown component that we previously separated out of Panacetin for testing.

Chapter 2 The Components of Matter Elements‚ Compounds‚ and Mixtures: An Atomic Overview An element consists of only one kind of atom. An element is one kind of substance – the composition is fixed. Each element is unique because the properties of its atoms are unique. Molecules are structures containing two or more atoms chemically bound together. Diatomic molecules are two-atom molecules such as elemental oxygen. A compound is a type of matter in which two or more different elements are chemically
