Nitrates

This is a very small amount of nitrate and is justifiable due to the nitrification and oxidation processes. The parameters state that a healthy level of nitrates that should be found in freshwater is less than 1mg/L. As previously shown, the resulting nitrate level is 1.1735mg/L. Therefore showing that the nitrate level is slightly higher than recommended but is still healthy in terms of the biological health of the creek. This could be considered a the outlier of the group in terms of the recommendations as it is the only factor which does not positively correspond with the parameters and recommended data levels for freshwater creeks. This is because of two reasons. One is nitrification, which was previously stated and explained. The other is because of commercial fertilizers used by local farms. These fertilizers contain ammonium nitrate (NH4NO3), which is carried through the land and dispersed into the water, and as ammonium nitrate (NH4NO3) and water ( ) are both polar molecules, the ammonium nitrate dissolves into the water. When ammonium nitrate is bonded to dissolved oxygen ( ), the oxidation process converts the compounds into dissolved nitrates ( ). This means that the fertilizers in the local sugar cane farms are negatively effecting the nitrate levels in the water. The prior three tests over the previous two years have resulted in 0mg/L of nitrates occurring in the water. From a chemical standpoint, this means that the water…

year the sky is full of gigantic grey clouds filled with rainwater. During those nine months there's usually a relatively constant amount rainfall covering Bothell. Many citizens who have been experiencing the phenomena of rain for countless years are unaware that there's a difference in rainwater from previous decades. The pH of rainwater has been slowly decreasing (becoming more acidic) due to pollutants in the air. Industrial areas that are releasing nitrates (NO3-) and sulfates (SO42-) are…

researching and testing multiple compounds, I have concluded that Ammonium Nitrate is the best compound for a cold pack. One of the most important factors in choosing a compound for a cold pack is how cold it will get, because of this, Calcium Chloride is a bad choice for a cold pack as it is an exothermic reaction and releases heat. On the other hand, Ammonium Nitrate had the largest drop in temperature, with a drop of 9.6° celsius. This is good for a cold pack as a cold pack is supposed to…

A. After having viewed the 'Anatomy of a firework' interactive answer the following: What are the different parts that make up a firework? Fireworks have a few different parts such as Potassium Nitrate, Charcoal, and Sulfur and they use different chemical compounds to create three kinds of results: A tremendous "boom" A bright light Heat What is the recipe for black powder? Why do you think Potassium Nitrate, Charcoal, and Sulfur become explosive after they are ground together? Black…

Rising Nitrate Levels in the Floridian Aquifer The Floridian Aquifer is often referred to as the life blood of the state. With over 1,000 springs throughout Florida being fed freshwater from depths of up to 2,000 feet, no other aquifer in the United States can compare. Many of the aquifer fed springs, that once flowed millions of gallons of crystal clear 72-degree water, are now nothing more than algae filled mud holes. The aquifer is in peril, and one of the main contributors to the decline in…

Solutions should be the cations of cupric nitrate, ammonium nitrate, zinc nitrate, calcium nitrate, aluminum nitrate, silver nitrate, ferric nitrate, and plumbous nitrate. The other seven solutions should be the anions of sodium hydroxide, sodium carbonate, potassium sulfate, sodium iodide, sodium phosphate, sodium chloride, and sodium chromate. Divide students into groups of two. Provide a bin of paper towels for the students to empty their well plates. Students: Obtain a pair of safety…

Aim The objective of the experiment is to explore the process of simple analysis techniques and representative sampling in determining soil nutrient levels. Soil samples collected from Flinders Campus were used to determine their pH, salinity, ammonium, nitrate, phosphate, and nitrite levels. Introduction Unless there is a specific problem detected, the most common reason for undertaking soil analysis is to detect the levels of essential nutrients (Guo, 2009). The commonly analysed nutrients in…

This test is performed on organisms to see if it has the enzymes to reduce the Nitrate to Nitrite. To run the test, it will require using two colorless chemicals (so make sure you are paying attention) that will either change the color of the organism by the interaction of the new chemicals with the enzymes found in the unknown organism. So, if the organism has the capability to reduce the nitrate to nitrite the solution in the test tube will turn red almost immediately and the organism is…

2.3 Dissimilitary nitrate reduction According to Croal et al., (2004), bacteria such as Shewanella oneidensis can reduce Nitrate (NO3-) for the purpose of assimilation and in this research is consider only those that engage in dissimilatory nitrate reduction Ammonium (DNRA). Which is the process of using (NO3-) as a terminal electron acceptor in anaerobic respiration. (NO3-)-reducing bacteria is mainly have habitat in freshwater and marine environments. They play significantly affect in the…

Uses of Nitrates and Nitrites in food Nitrates and Nitrites in the food industry Nitrates and Nitrites or more commonly known as curing salt or pink salt, is usually used in foods such as hot dogs, sausages, ham, meat loaf, bacon and other deli meats. Nitrates and nitrites in the food industry are more commonly found in a charcuterie, which is a store that sells cooked meat in direct translation. We use nitrates and nitrites in our foods because they provide a more vibrant colour to…
