are brought from the Pre-weigh area for batching, the compounder assigned the batch must verify the chemicals and quantities brought from the Pre-weigh department and the weigh tickets must be affixed to the back of the Work Order (do not throw away). 5.4.3.2 If there are any missing tickets stop the process and notify your supervisor for prompt follow-up, you may resume once the ticket and chemical is verified (this is an urgent matter and must be addressed immediately by informing the…

As briefly mentioned before, atropine acts as an antagonist on acetylcholine because its chemical structure is similar to acetylcholine. Thus, structure is an important feature of the atropine molecule that is imperative to understanding its effects on the body. Although today’s chemists know the chemical structure of atropine, the conformational flexibility of the molecule is still poorly understood. A conformation is any three-dimensional arrangement of atoms within a molecule that results…

5861 What is the identity of the unknown hydrate? Hydrates are pure substances that contain water molecules embedded in their crystal structures. When a hydrate is heated the water molecules evaporate leaving behind a solid known as anhydrous. The identity of a hydrate can be found by finding out the percent water in the hydrate. The experiment was done in a manner to find the percent water in an unknown hydrate to identify the hydrate. The hydrates were BaCL2*2H2O, CuSO4*5H2O, CaCL2*2H2O, and…

Chromium (Cr) is one of the most toxic chemical compounds due to the common use of chromium compounds in industry in addition to its natural sources (Costa et al., 2003). Exposure to chromium occurs via contaminants found in drinking water and food, through air containing particulates or mists of hexavalent chromium Cr (VI) compounds, or through skin contact with soil at hazardous waste sites (National Institute for Occupational Safety and Health, 2013). Cr (VI) may be found in drinking water…

structure of an unidentified compound that was discovered in a local landfill. The group was called in to help determine the chemical and physical properties of the compound so we can let the people of the town know so it can be taken care of properly with or without further precautions to be taken. Another goal of this project was to devise the synthesis of the unknown compound. Experimental Design In order to determine the correct identity of our unknown compound, we first started with a…

the lab was to identify an unlabeled compound found in the chemistry stockroom to be able to dispose of it properly. This lab demonstrated the process of identifying an unknown compound as well as synthesizing the compound. Identifying the compound consisted of performing various tests to detect the chemical and physical properties of the compound and comparing it to the list of possible compounds. The tests conducted were the solubility test which the compound fully dissolved in water, the…

Identification of an Unknown Compound to Determine Proper Waste Procedures Department of Chemistry, Michigan State University, East Lansing, MI 48823 October 13, 2015 For completion of CEM 161 Section 009, under supervision of Abstract: In order to determine the identity of the compound we performed many experiments with a solution of the compound. These experiments included testing for all of the following ions; ammonium, halide, sulfate, carbonate, nitrate, and acetate…

Identifying Unknown Substance. Examining the physical characteristics of the available compounds in the lab was how possible compounds were eliminated from any or further testing. Based on how the compounds physically looked, it was almost for certain that calcium chloride was the unknown compound. However, another compound was used to test as well (ammonium chloride) since relying only on physical characteristics alone would not allow for proper experimentation. The unknown ended up being…

has the same chemical particles as a whole sample of the element. Everything in the world is made up of these tiny particles called atoms. Growing on our knowledge of the atom, if you combine two atoms chemically you produce a compound. The two different classifications of compounds include organic compounds or those that contain carbon atoms. An example of an organic compound is proteins, fats, carbohydrates, nucleic acids, and other compounds in living organisms. All other compounds are…

Between 1942 and 1953 there was active dumping of chemicals waste into the canal. Document submitted by Hooker to New York interagency task force of hazardous waste, showed that an estimate of about 21,800 tons of chemicals waste from the manufacturing process of the company was dumped in the canal. “These waste were mainly organic pesticide residues, waste solvents, fly ash and process…
