  • Dissolved 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…

  • Determining Soil Nutrient Levels

    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…

  • Floridian Aquifer Essay

    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…

  • Solubility Lab Report

    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…

  • Nitrates And Nitrite Essay

    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…

  • Nitrate Synthesis

    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…

  • Potassium Nitrate Lab

    The objective for this lab is to construct a solubility curve for potassium nitrate in water by measuring saturation temperatures for six different solution concentrations. We form a group of four and were assigned to work on series one while the other group work on series two. Throughout the lab, we set a hot bath water temperature at 85 degree celsius which affected how potassium nitrate dissolves in water and changed the saturation temperature. In addition, our group discovered that the mass…

  • Getting Fossil Fuels Off The Plate Analysis

    society, without pouring those chemicals, the soil is useless. So much energy is put into producing crops now, it’s outlandish. Too many machines that require fossil fuels to operate are used to get food to your house. Here’s the long and ridiculous cycle of growing, processing, and transporting a crop: First, you drive an oil-powered machine to plow the area. Then you drive another oil-powered machine to plant the seed. Then you irrigate by using water pumps powered by electricity. Where’s…

  • 2.2: Preparation Of Econazole Nitrate Nannoparticles

    econazole nitrate nanoparticles The econazole nanoparticles were prepared by nano-spray drying technique. Weighed amounts of econazole nitrate, carriers and stabilizers (table 1) were dissolved in ethanol (10 ml) followed by spraying through the Buchi® nano-spray dryer B-90 (Büchi Labortechnik, Switzerland). The nano-spray dryer was operated using inert loop B-295 system (Büchi Labortechnik AG, Flawil, Switzerland) operated using nitrogen gas with flow rate of 110 L/min. The spray drying…

  • Essay On Nitrate Test

    The nitrate test was conducted in order to see if nitrate was present. After the addition of two percent acetic acid the unknown had no color change (negative) and therefore the test could not be used for Pseudomonas species. In order to see if the unknown could use citrate as its sole source of carbon, a citrate test was performed. The media of the citrate test contained bromothymol blue, a pH indicator that would have turned blue if the if the organism had a positive reaction. However, my…
