Expt. 8.1 Thin Layer Chromatography (TLC) Analysis of Analgesics Krista Jinks CH 211L Section F 10/27/14 I. Abstract: The objective of this experiment was to analyze analgesic tablets by TLC to determine what analgesics they contain. The analgesics that could be in the tablets included ibuprofen‚ acetaminophen‚ aspirin‚ and caffeine. Through the use of TLC‚ unknown substance #62 was found to be Bayer Aspirin because it only contained aspirin. II. Introduction: 1. Briefly describe

Amines and Amides Amine - an ammonia molecule (NH3) in which one or more H atoms are substituted by an alkyl or aromatic group. Amide - an organic compound with a carbonyl functional group (C=O) bonded to a nitrogen atom. Amines are the smaller and simpler products of the decomposition of larger and more complex organic compounds like proteins. They often have foul odours‚ as do many nitrogen compounds‚ such as the smell of rotting fish and decomposing animal tissue and are produced by

of potential causes for smelly water‚ and the following are some of the most common. Chlorine Almost everyone is familiar with the bleach aroma of chlorine in the water. It may appear stronger at times‚ and this is typically due to excessive chlorination in public water sources. Chlorine is used by water treatment facilities for water disinfection and treatment. A Benjamin Franklin plumber in Arlington can provide the solution for chlorinated water with water filtration‚ eliminating not only the

Experimental Design (70 points) Title | How the Volume of the Slurry Mix Effected the Biogas Generator | Type of Experiment | Experimental | Background Information | Methane is a chemical compound with the chemical formula CH4. It is the simplest alkane‚ the main component of natural gas‚ and probably the most abundant organic compound on earth. For this experiment we had created a bio gas generator. A biogas generator is any gas fuel derived from the decay of organic matter‚ as the mixture of methane

All surface water and some groundwaters require treatment prior to consumption to ensure that they do not represent a health risk to the user. Health risks to consumers from poor quality water can be due to microbiological‚ chemical‚ physical or radioactive contamination. However‚ microbiological contamination is generally the most important to human health as this leads to infectious diseases which affect all populations groups‚ many of which may cause epidemics and can be fatal.

Ethers have much lower boiling points compared to alcohols of comparable MWs. BPs of ethers increases with increasing MW. BPs of isomeric ethers increase with increasing alkyl chain length. BPs of ethers are about the same as those of alkanes of comparable MWs. Solubility of ethers in water is comparable to that of alcohols. As chain length of ethers increases‚ solubility in water decreases. Branching of the alkyl chain results in greater solubility since London forces are weaker
