Nitrate

variety of atmospheric and water pollutants. Fertilizers have high concentrations of soluble nitrogen and phosphorus compounds, and animal wastes contain high levels of nitrate. The use of fertilizers thus can produce high nitrate (a nitrogen-oxygen compound) and phosphate (a phosphorus-oxygen compound) in natural waters. Nitrate can combine with hemoglobin so that oxygen transport in the body is inhibited. This is a potentially serious threat to infants. Water high in phosphorus can stimulate…

1. EXECUTIVE SUMMARY Every organism needs food to live. Importance of food has increased enormously in case of human. With the rapid growth of the population the demand of food has also increased. Fresh and unprocessed food have very less shelf life. The increasing demand of food also increased the need of extending shelf life of foods. Different natural and chemical substances called food preservatives are being used to increase the shelf life of food which prevents microbial growth and…

steps 7-9 with Copper Chloride and the Copper metal piece. Attach one end of the red wire onto the 5 lead and the other end onto the top of the copper material. Rip a thin strip of paper from a paper towel and dip said strip into the Potassium Nitrate solution until the strip is fully submerged. Place one end of the drenched strip of paper, or ‘salt bridge’ into the Zinc solution, and another end into the Copper solution. The set up should look similar to the diagram…

reaction has taken place. Formation of precipitate, which is a solid formed in a chemical reaction. Precipitate can take place when solutions containing ionic compounds are mixed and an insoluble product forms. An example is mixing is mixing silver nitrate and sodium chloride in water, which will cause silver chloride to precipitate out of the solution as a solid. Color change can also indicate a chemical reaction has taken place. An example…

When it comes to dealing with analytical chemistry, the main focus is the composition and structure of matter, and the processes utilized to do so (Analytical Chemistry, n.d.). A lot of the times in chemistry people want to explore a compound, analyzing it to see what components are used to create that said compound and there are many different methods that can be used to help isolate those different components. The purpose of this lab is to utilize gravimetrical analysis to isolate and…

changes, followed by and several other cities. These areas “prohibited ships carrying ammonium nitrate from entering their harbors” (Ferling, 1996). Additionally, the Coast Guard began banning ships carrying explosive carriers from docking in thickly populated areas four months after the disaster (Ferling, 1996). New standards were developed regarding the storage, handling, and shipping of ammonium nitrate and prohibiting its storage near known reactive materials (Burke, 2007). Refineries in…

the area, affects the creek and its ecosystem over time. Monitoring the water chemistry of a creek enables scientists to ensure the area is relatively pollution free, continues to follow the normal data trends for pH, conductivity, temperature, and nitrate concentration measurements, and…

identify the anion, we needed to perform four anion reactions: chloride, sulfate, nitrate, and carbonate. To identify a chloride, equal amounts of the unknown solution, 6M HNO3, and AgNO3 are mixed together and if a white precipitate is formed, the test is positive. To identify a sulfate, equal amounts of the unknown, 6M HCl, and BaCl2 are mixed, and the presence of white precipitate yields positive results. To identify a nitrate, mix 1 mL of the unknown with 3 mL of H2SO4 and cool the solution.…

#3). The Voges-Proskauer test gave a positive result. This positive result is “indicating the presence of diacetyl, the oxidation product of acetoin (Acharya, ref #2). The last test performed was the nitrate reduction test, which determined if the organism could reduce nitrate to nitrate via nitrate reductase enzyme (Welcome, ref #2). After this test was completed, I got a positive result. K. pneumoniae can grow on any ordinary nutrient media. When introduced to solid media, will form protruding…

A Rocket is a projectile that can operate on it's own without oxygen by the combustion of it's contents. Rockets are particularly interesting because it has transported mankind where they have never been before. That is why this project is on Rocketry, but with small scale rockets. The purpose of this project is to see if a homemade Baking Soda Rocket can equal the endurance and/or the height of a Hobbytown Rocket. Though it is important to know the history of rockets and how they function, and…
