Nitrate

prepare silica solution, zinc acetate solution and zinc nitrate solution. For the zinc acetate, adding 2-propanol to the hydrated zinc acetate will result in a white solution with some precipitations of zinc acetate in the bottom of the beaker, then by adding 2.1 grams of diethanolamine, ratio is 1:1, the solution will be transparent; due to the effect of diethanolamine which increases the pH of the solution, make it basic. Dissolving zinc nitrate in 2-propanol is much easier than zinc acetate,…

because we expected it to have the highest value of nutrients for plants to grow in and a soil composition that is fit for food production (ex. Water Holding, etc). To test our hypothesis, we ran tests measuring Percent Water Content, Organic Material, Nitrates, Phosphates, Potassium, and Percent Sand, Silt, and Clay. The first test we conducted was the Percent Water Content; to determine the value, we massed soil in a tin cup, heated the tin cup and soil in the microwave for 24 hours, and…

Discussion Questions General 1. Ammonification is the microbial degradation of nitrogenous compounds resulting in ammonia. Nitrification is a process by which ammonia is oxidized to nitrite and then nitrite is oxidized to nitrate. Denitrification is a process by which nitrate is converted into nitrogen gas or nitrous oxide by denitrifiers. Nitrogen fixation is a process by which atmospheric nitrogen is converted into ammonia by symbiotic or non-symbiotic mechanisms. 2. The distinguishing…

established which has resulted in an increase of water pollution with nitrates of groundwater wells which is the primary source of drinking water for many residents in the lower valley. Nitrate can be found in the water and soils as a natural form of nitrogen and it’s usually found in shallow groundwater with normal concentrations up to 1.1 mg / L. However, when higher levels are found, it’s mostly due to human activities. Nitrate chemical characteristics made them highly soluble in water and…

for intake. These excess levels of nitrate found in water are extremely hard on the human body, and can be lethal in infants (Holme). Mixing water with formula to feed a baby is a perfect example of how nitrites can enter an infant’s immature digestive system. In 1999, a 3-week old in Wisconsin suffered from methaemoglobinaemia, also known as “blue baby disease”. This disease was caused by high levels of nitrates in the family’s well water (Golden). When nitrates (converted to nitrite) are in…

with the hydrochloric acid to form zinc chloride and hydrogen gas (equation 10). For the first double replacement reaction, barium nitrate Ba(NO3)2 is combined with sodium hydroxide NaOH. During the reaction, the mixture is cloudy and white while there are small particles of precipitation in the solution of the test tube. After the reaction, the mixture of barium nitrate and sodium hydroxide remains cloudy and the precipitation is…

store to medical grade items. Nitrates and other nitrate compounds are the most common medical grade inhalants. Nitrates relax smooth muscles that control the diameter of the blood vessels. This means your eyes would dilate, blood vessels enlarge, and your bowels loosen. The mental effects are warming and giddy sensations. It also has a sexual sensation aspect. Skin sensitivity, exhilaration and acceleration of sex organs is common with nitrate inhalants. Some nitrate inhalants are industrial…

particle surface of silver nitrate particles to allow them to interact. Finally, silver nitrate can aggregate. The silver nitrate combined with D-glucose, sodium citrate, and heat forms an aggregate. The citrate binds with the particle coating and dispels the repulsion between silver nitrate nanoparticles. The nanoparticles then form an aggregate-- a loose group of particles. Batch C was resistant to aggregate formation. It did not include glucose, which reduces the silver nitrate and allows it…

3 M acetic acid; which means #68 was 0.1 M aluminum nitrate. #62 was a weak acid that did react with NaOH forming brown precipitate, so it was 0.1 M silver nitrate. Both of #63 and #69 are weak acids, but, #63 did react with 0.1 M silver nitrate, so it was #63 is 0.1 M zinc chloride, which means #69 is 0.1 M lead nitrate. #67 did react with 0.1 M silver nitrate, where #64 did not. In addition, #67 formed white precipitate with 0.1 M lead nitrate, so #67 was 0.1 M sodium chloride. So the #64 was…

to the stream and seeing how much nitrate, phosphates, dissolved oxygen, turbidity, temperature, and pH is in the water. The stream team will look at the effect on water quality, the effect on plants and animals, the acceptable levels for swimming, sources and sources categorized, the best management practices, whether the sources are point source, or nonpoint source pollutants, and the test results. The stream team will be doing all of those topics over nitrate, phosphate, dissolved oxygen,…
