Potassium nitrate

Methods Paper no.:151.708 Topic of research: The effect of dietary nitrates on weight maintenance in obese population following a 10% weight loss TITLE The effect of dietary nitrates on weight maintenance in obese population following a 10% weight loss BACKGROUND Dietary nitrates are inorganic inert anionic compounds in fruits, vegetables and cured meats. About 80-85% of the nitrate in our diets is derived from

obtain nitrogen in the form of nitrate and ammonium from the soil. Too much nitrate can cause a negative effect on the plant including nitrate toxicity. High levels of nitrate are not only bad for plants but can also be dangerous to animals or humans in their presence. Here I discuss the scientific evidence of the effects of nitrate accumulation on plants and the

That temperature varies through the types of weather. For pH - using strips, The pond had a pH of 4. For the pH - using tablets, the pond had a pH of 7. The Voyager ponds dissolved oxygen level was 4ppm. The nitrate level for the Voyager pond was 0 ppm. The ammonia levels was 0 ppm for the Voyager pond. The turbidity of the Voyager pond was 20 JTU. The hardness of the Voyager pond was 20 gpg. The different types of bioindicators in the voyager pond were algae

improve water quality. In a laboratory controlled environment, the PHA fibrous mat successfully denitrifies the water at a quick rate. From an incubation completed in the Keck Lab, the experimental fibrous mat of PHA is shown to be able to drop the nitrate levels in water to about one-fourth of the original concentration in less than 20 hours. Due to the success in a small scale lab experiment, there is a need for me to test the PHA fibrous mat in a large scale environment to successfully assess its

Enzymes catalyze biological systems by speeding up the chemical reactions included. Enzymes developed from the peroxidase that is obtained from the different roots reacts with the hydrogen peroxide, which releases H2 and water. The extra hydrogen is indicated by the color change of the solution that is used to measure the rate of enzyme activity. When the rate of enzyme activity was high, the activity always occurred in the roots in the beginning stages of their development. However, when the rate

Discussion: There are numerous ways of isolating and purifying a substance, and an investigation of the differences of each procedure were performed. In two different procedures, lead nitrate and potassium iodide were used to isolate and purify pure solid lead iodide, and the differences in the limiting reactant and solid lead iodide was observed. The amount of solid lead iodide was calculated by the measuring the mass of which the solid lead iodide was created in before and after the purification

Date Performed: July 30, 2012 EXPERIMENT NO. 10 COMPOSITION OF POTASSIUM CHLORIDE ABSTRACT The aim of the experiment was to look for the percentage composition of the elements present in the decomposition of potassium chlorate (KClO3) and to find out what the residue after heating was. After performing the experiment the researchers found out that there were about 66.14% of potassium chloride (KCl) in KClO3, and they also deducted that the residue was actually KCl. _____________________

volts of electricity, meaning the compound contained both positively and negatively charged ions that move around to conduct the electricity. Potassium Sulfate has a solubility of 1 g in 8.3 mL of water, which matches with the results of the unknown being soluble in water (The Merck Index). Ionic compounds, a form of polar compounds, are soluble in

The Composition of Potassium Chlorate Objectives The objectives of this laboratory are: a) To experimentally determine the mass percent of oxygen in the compound potassium chlorate (KClO3) via the thermal decomposition of a sample of potassium chlorate. b) To qualitatively demonstrate that the residue resulting from the decomposition of potassium chlorate is potassium chloride. Background All compounds consist of elements chemically combined in fixed proportions – they obey the Law of Constant

Part A: Diffusion on a liquid in a liquid. I did an experiment with three different glasses of tap water from the faucet. All three cups measured the same which happened to be 13 cm from the top of the cup to the bottom of the cup. I let the water settle, and sit for about an hour so the temperature was the same for all three cups. I then placed one drop of food coloring into the first glass and waited for the coloring to reach the bottom. I calculated 93 seconds. I then went to the second glass
