Sulfuric acid

elemental form after a chain of reactions. This experiment is very dangerous because of the reactions between the strong acids and bases. In this experiment I performed a series of reactions starting with copper metal and nitric acid to form copper (II) nitrate. Then I reacted copper and several other solutions such as, sodium hydroxide, sulfuric acid, ammonium hydroxide, and hydrochloric acid to form precipitates. In conclusion my percent recovery

positive charge. Stage two Figure 2. Stage 2 of the nitration mechanism The second stage involved a hydrogensulphate ion, HSO4-, which was produced at the same time as the NO2+ ion. This removed a hydrogen from the ring to form sulphuric acid - the catalyst had therefore been regenerated. The electrons which originally joined the hydrogen to the ring were now used to re-establish the delocalised system. Table 1. Observations from the experiment proper Observations: 89 mL conc. H2SO4

after six months the emission rates slowly declined. The CO2 and H2O vapour released during eruptions does have a marginal effect on the climate, but by far the most influential gases on Earth’s climate are the sulfuric gasses released. Effects of Volcanic SO2 on Climate The most common sulfuric gas released from volcanic eruptions is SO2. The effect that SO2 has on climate is much more complicated than other volcanic gasses such as CO2 and H2O vapour. SO2 also affects Earth’s climate much more severely

the lead in the clean-up. It was easy to identify the hazards: contaminated water, contaminated soil, possible area collapse, and the lead laced chat piles. To begin the Superfund site cleanup the EPA started with monitoring of the surface water, acid mine water discharge, and

investigation will argue that the Vitamin C level in Golden Circle Pineapple juice will decrease over time. Chemical information and safety surrounding the use of these substances. Previous scientific work: CHEEKY NANDOS Vitamin C: Vitamin C (ascorbic acid) is a water-soluble vitamin, which is needed by the body to form collagen in bones, cartilage, muscle, and blood vessels. Dietary sources of vitamin C include fruits and vegetables, particularly citrus fruits such as oranges. Severe deficiency of vitamin

disposable pipettes, a stirring rod, a filter flask, filter paper, a Büchner funnel, distilled water, a watch glass, and litmus paper. The chemicals used in this experiment include 6M of HNO_3 (Nitric Acid), 6M of NaOH (Sodium Hydroxide), 3M of H_2 SO_4(Sulfuric acid), 6M of HCl (Hydrochloric Acid), Zinc, and Copper turnings. The experiment began with setting up the first apparatus by placing the 50 mL beaker on the hot plate and attaching the beaker to the ring stand. Then a fume hood was

the crude product is washed with sulfuric acid, water, and sodium bicarbonate to remove any remaining acid or n-butyl alcohol. The primary alkyl halide halide n-butyl bromide is prepared by allowing n-butyl alcohol to react with sodium bromide and sulfuric acid. The sodium bromide reacts with sulfuric acid to produce hydrobromic acid . Excess sulfuric acid acts to shift the equilibrium and speed up the reaction by producing a higher concentration of hydrobromic acid. The

Abstract The concentration of ethanol in vodka was determined by back titration. A known amount of excess potassium chromate was added to the vodka sample to convert ethanol into acetic acid by oxidation. The amount of leftover chromate was determined by titration with iron (II) solution, prepared from dissolution of ferrous ammonium sulfate. Using the amount of chromate added to the vodka solution, the amount of chromate reacted was determined and used to find the amount of ethanol in the sample

The Copper Basin of southeastern Tennessee is an area that is climatically unique with a rich history rooted in copper mining. It is thought that man is responsible for the total destruction of the environment over this large area, but it is mostly contributed to the exclusive location. The Copper Basin was susceptible to negative environmental effects due to its topographical, geological, climatic, edaphic, and meteorological location. However, the copper mining had a transformative effect on the
