Science Experiment On Odor Changes Of Various Chemicals
The purpose of my experiment was to research and determine why the odor changed after mixing several controlled substances. The experiment involves esterification, which is the reaction of carboxylic acids and alcohol’s to form esters. First, I put 4 ml of vinegar in a test tube and noted the odor, I then added 1 ml of ethyl alcohol and noted the odor. Lastly, I was to add seven drops of sulfuric acid while stirring over a Bunsen burner. I then repeated this process with salicylic acid and methyl alcohol. In this project, my main objective was to accomplish why the odor changed after my mixtures were warmed. My hypothesis for this experiment was that the different smelling chemicals, ...

my project, I researched vinegar. Vinegar is a sour liquid with a pungent odor, containing acetic acid, and is made by fermenting dilute alcoholic liquids such as cider, wine, or other fruit juice. Vinegar is used as a condiment, preservative, and in certain medicines (2: 1214).
Ethyl Alcohol is also used in medicines. The formula for this is C2H5OH. It is a colorless liquid with mild characteristic odor. Also known as ethanol, the compound is miscible in all proportions with water or ether (1: 361-362). When ignited, ethyl alcohol burns in air with a pale blue, transparent flame. While burning, it produces H2O and CO2. The vapor forms an explosive mixture with air and is used in some internal combustion engines under compression as a fuel (2: 478-479).
Natural fermentation is the oldest process for making ethyl alcohol and still constitutes the principle means for creating the alcoholic content in beverages. Except in connection with other alcohol containing products, ...

and these include the manufacturing of fertilizers, chemicals, inorganic pigments, petroleum refining, making of explosives, and in nonferrous metallurgy (1: 909). Fundamentally, there are two kinds of sulfuric acid plants. Those that use dry gas (sulfur burning) process, and those that use the wet gas process. In the first type, the raw materials are elemental sulfur and water. In the second type, the sulfur dioxide feed may come from a variety of sources. These sources include metallurgical smelters, pyrite roasters, waste acid decomposition furnaces, and hydrogen sulfide burners. In these plants, the SO2 gas stream enters the acid plant containing a large amount of water ...
