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

Components of Panacetin: Introduction: Of the three components likely to be present in your sample of Panacetin (aspirin‚ acetanilide‚ and starch)‚ only starch is insoluble in the organic solvent dichloromethane (or methylene chloride)‚ CH2 Cl2. If a sample of Panacetin is dissolved as completely as possible in dichloromethane‚ the insoluble starch can be filtered out‚ leaving acetanilide and aspirin in solution. The purpose of this experiment is to extract the components of Panacetin. Although

preparation Panacetin‚ a proposed type of pain-killer. Panacetin is typically made up of sucrose‚ aspirin‚ and acetaminophen‚ but the third component in this experiment is unknown. The unknown component is suspected to be a chemical relative of acetaminophen‚ either acetanilide or phenacetin. Using techniques such as extraction‚ evaporation‚ and filtration‚ the three components will be isolated based on their solubilities and acid-base properties. The percent composition of Panacetin will also be

Separating The Components of “Panacetin” Observations Most natural products and many commercial preparations are mixtures containing a number of different substances. To obtain a pure compound from such a mixture‚ you must separate the desired compound from the other components of the mixture by taking advantage of differences in their physical and chemical properties. Acidic or basic substances are often converted to water-soluble salts‚ which can then be separated from the water-insoluble

Experiment 1: Simple and Fractional Distillation of a Binary Mixture Aim: The aim of this experiment is to perform a simple and a fractional distillation and separate a mixture containing two liquids‚ cyclohexane and toluene. Post Lab: At any given temperature a liquid is in equilibrium with its vapor. This equilibrium is described by the vapor pressure of the liquid. The vapor pressure is the pressure that the molecules at the surface of the liquid exert against the external

ASSESSMENT ONE Deconstructing the Crime Problem DSS_4_DCP 12/13 Débora Rodrigues Ferreira Baptista Forensic Science with Criminology – First Year As we can see in the figure above‚ the CSEW (Crime Survey for England and Wales) estimate is much higher than the police recorded crime values. This is due to the fact that most crimes do not come to the attention of the police‚ usually because people do not report them for various reasons‚ such as distrust

The woman in the video is thinking‚ that she is getting her answers corret‚ which isn’t true. It was just a way the man used to try to impress the woman‚ by telling her she was correct.
