  • The Pros And Cons Of Nitric Acid

    and academia for sustainability. Oxidation can be stated as the technology which converts petrochemical supplies to materials which has higher oxidation state. However, this process causes many problematic issues due to its many drawbacks. In chemical industry, nitric acid is the most common industrial oxidant (Noyori, Aokib and Satoc, 2003). Nitric acid has been used for many years as an oxidant. It has the characteristics to ionise readily in a solution. Nitric acid can react with metals, hydroxides, and oxides. (Frane, Herber and Knowles, 2015). Since Nitric acid is a powerful oxidant, it can react with non- metallic compounds and cause explosion contingent on the temperature, concentration, and reducing agent (Nitric acid, 2015). Even though nitric acid is relatively inexpensive to use as an oxidant, it can produce various nitrogen oxides. Nitrogen oxides can be harmful for ecosystem and human as it has cynical impact on these two. Moreover, NOx can have significant Greenhouse effect causing depletion of ozone layer. Therefore, it cannot be considered as clean, safe oxidation process (Noyori, Aokib and Satoc, 2003).…

  • Double Salt Lab Report

    Chemistry Stockroom), 6 M HCl (EIU Chemistry Stockroom), 10% BaCl2, 6 M HNO3 (EIU Chemistry Stockroom) Equipment – Ocean Optics Spectrometer USB4000, Logger Pro Procedure – In order to find the mass percent of the sulfate, the sulfate needed to separate itself from the rest of the double salt. To do this, experimenters began by weighing out 0.998 g of the double salt into a 250-mL beaker. They then used the graduated cylinder to add about 150 mL of deionized water and 2 mL of the 6 M HCl into…

  • Adipic Acid Case Study

    Adipic acid is mainly use as monomer in manufacture Nylon 6/6 fiber, plasticizer, grease, polyurethane etc. There are several countries in the world that manufacturing the adipic acid. But there also countries that just is a supplier for this adipic acid to any factory that need adipic acid in their countries. The main countries that produce adipic acid are United State of America and also China. Almost ninety percent of adipic acid manufactured in United State of America is used to produce…

  • Copper Created Lab Report

    Then a piece of filter paper was put into a Büchner funnel which was attached to the filter flask. Then the water to the aspirator was turned on and the remaining solids were transferred to the funnel. Then the copper was rinsed with distilled water and kept on the aspirator to until it was dried. Lastly, the copper was put on a watch glass to weigh the amount of copper left at the end of the experiment. Results and Discussion: Cycle step 1 of the experiment was begun by weighing out about 250…

  • Taking A Look At Acid Rain

    Introduction/ what is Acid Rain? Acid rain, or acid precipitation is a term used to describe any form of precipitation with a pH of less than 5.6. In recent years, the effects of acid rain are being experienced on a global scale with widespread environmental effects. Primarily, acid rain is caused by emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) from the combustion of fossil fuels. However, even pure rainwater is slightly acidic (pH of 5.6-6.5) due to the reaction between H2O and…

  • Acid Rain Essay

    Acid Rain is best described as any form of precipitation with high levels of nitric and sulfuric acid. Acid rain or acid deposition is the result of burning of fossil fuels. About two-thirds of SO2 and one-fourth of NOx are released into the air; it comes from electric power generators. These chemicals react would react with water, oxygen, and other substances to form delicate solution of sulfuric and nitric acid to form acidic pollutants. The source of sulphur dioxide comes from volcanoes,…

    relaxation occurs by pumping Ca²⁺ out of the cytoplasm and back into the SR or out of the cell. As the amount of Ca²⁺ decreases, then Ca²⁺ will unbind from calmodulin which would deactivate the MLCK. Relaxation can also occur by inhibiting myosin light chain from undergoing a conformational change and allowing myosin and actin to bind to each other. This inhibition can be attributed to myosin light chain phosphatase which is activated by protein kinase G (PKG) (Forstermann et. al 2006). PKG is…

  • Sulphuric Acid Case Study

    3. SAFETY AND ENVIRONMENTAL ASPECTS OF SULPHURIC ACID PRODUCTION 1. Safety Aspects 1. Basic Safety Aspects due to Physical properties and behaviour of Sulfuric acid. Basically, we know attention is paramount when adding water to a highly concentrated acid and this is the case with sulphuric acid which is highly risky. Sulfuric acid can have serious adverse effects like burns if it contacts the skin. This is due to the dehydrating properties of the acid on organic materials. Also, when the…

    2012). The pH levels of aquatic environments are important because it affects the physiology of animals by changing their behaviors. The ion concentrations associated with the water and the organism’s survival can also be affected (Mahassen, El-Deeb Ghaxy, 2011). This includes increased levels of basicity. The NaOH spills can also contribute to changing pH levels. This is a very popular compound used by chemical industries. NaOH is significantly found in the water as its ionized version, Na+ and…

  • Testing Water Quality

    The nitrogen in the ecosystem is from natural events. Nitrates are mostly ammonium and nitrate. This compound is used in the ecosystem for the growth, repair, and reproduction of plants. Nitrogen appears in a lot of natural processes. Some plants take atmospheric nitrogen and convert it to nitrogen that they can actually use. By burning forests, grasslands, and fossil fuels this releases nitric oxide into the air. When it goes into the air it can become acid rain and photochemical smog. This is…
