    substance was formed or a substance that is not aqueous was formed. The reactions that did not form a precipitate were DNR, which means that they did not react. At station one barium chloride and potassium nitrate did not react but barium chloride and silver nitrate reacted to form barium nitrate and silver chloride. The precipitate at station one was silver chloride. Both reactions at station two did not react. Station three had a reaction occur between sodium carbonate and calcium sulfate…

    water sources with phosphate, nitrate, and other chemicals has become a big problem in today’s very industrialized world. Different chemical products and fertilizers leak nitrate and phosphate into rivers and lakes causing an explosion of algae growth in a process called eutrophication that results in low oxygen levels in the water. These low oxygen levels can cause a decrease in aquatic life and destroys the ecosystem of the water (1). One of the main ways that nitrate and phosphate are able to…

    Rivers and other water sources are being polluted with nitrates, especially the Raccoon River in Iowa. Nitrates are dangerous and can come from rural farms to urban cities. Nitrates come from fertilizers used on farms. Rain and storms cause the nitrates to flow into rivers and creeks. Many farmers do not know this. “The river was just water, as far as we were concerned”, says Seth Smith, an Iowan farmer. Most farmers did not know that the nitrate levels in rivers were important. These levels…

    week over the next 4 weeks. Pot A (phosphate limitation group) was given a phosphate reduced Hoagland’s solution, whereas Pot B (nitrogen limitation group) was watered with nitrate reduced Hoagland’s solution. Pot C (control) is the control plant as it was given standardized fertilizer regime using normal concentration nitrates and phosphates. All plants were grown in a growth chamber at a temperature of 22°C, the light intensity of 180 ue, photoperiod of 16 hours and humidity of 70%.…

    creek. The creek was a safe place for the animals living in the creek. The water speed of the creek was normal not to fast and not to slow. That's why I think the creek is not polluted. There was some nitrate in the creek. The nitrate absorbs oxygen and that's not good for the animals. The nitrate is actually dangerous to the creek and the critters living there. It is also dangerous to the water flow. It is also dangerous for the environment. The phosphates are found in some detergents but not…

    was determined that when the nitrogen is provided to the spores in the form of nitrates or nitrites, germination of fern spores can be inhibited or completely stopped by using higher concentrations (Milan and Whittier, 1990). On the other hand, when the nitrogen came from ammonium, the germination of fern spores increased (Milan and Whittier, 1990). The experiment determined that the effects of nitrogen from nitrates/nitrites and ammonium had the opposite effects on the germination of the fern…
