    Sulfuric acid or “Oil of Vitriol” is a clear, oily and strong acid with a chemical formula of H2SO4. It is water soluble and odorless. It is highly corrosive to most metals and biological materials. It is usually used in the liquid form and often diluted with water or other chemicals for use. It is estimated that by 2012, world production of sulfuric acid would reach over 250 million tons a year. The History of Sulfuric Acid The first mentions of sulfuric acid in history are somewhat lost

  • Phenol-Sulfuric Acid Analysis Essay

    740 Words  | 3 Pages

    The results of the phenol-sulfuric acid analysis conducted in this experiment suggest that the data acquired was relatively precise but inaccurate with respect to the given carbohydrate concentrations of the soda and Gatorade samples. Using a standard curve generated from a glucose solution with a known concentration, the carbohydrate concentration of the samples was determined (in terms of glucose) and a low coefficient of variation was calculated. However, a high percent relative error was apparent

    Nitration of Bromobenzene Raekwon Filmore CM 244 Section 40 March 27, 2018 Introduction: For this experiment, nitration of bromobenzene was the focus of the lab. The benzene is an aromatic compound and when it reacts with wither a mixture of sulfuric acid or nitric acid creates what is known as a nitro group. The formation of the nitro group is possible because it is an electrophilic aromatic substitution reaction. The creation of the nitronium ion is shown below: The reaction with the nitronium ion

    observed. Copper wire was dissolved in nitric acid. NaOH was then added to the dissolved copper solution, precipitating into Cu(OH)2. The precipitate was then placed on a hot plate and stirred until it became CuO. After sitting , the CuO was decanted twice, and H2SO4 was added. Zinc was then added to the solution to reduce Cu2+ back to its original form, and any excess Zinc was decanted. The liquid was decanted and the solid was washed with H2O to wash away any acid, and the solid was

    mined, phosphate rock is separated from particles of sand and clay and sent to a processing plant. These processes are usually wet to enable material transport and to reduce dust. Phosphate rock is THEN mixed with sulphuric acid to produce weak phosphoric acid. This phosphoric acid is mixed with various other minerals to produce liquid or solid fertilizers. Theses process vary with respect to the fertilizer being produced. Frequently manufactured fertilizers are triple superphosphates (SSP, TSP) and

  • Percent Cu2 + In A Mineral Sample

    931 Words  | 4 Pages

    Purpose/ Methods The purpose of this experiment was to determine the mass percent Cu2+ in a mineral sample (Malachite), and a rock sample (copper ore). Through the process of spectroscopy, the students were able to determine the percent of copper that each sample yielded. The students were also able to apply the information to the theoretical value of copper in malachite to determine the percent error of the mineral mass percent. Furthermore, the methods used in the experiment provide insight

  • Analysis Of Phenanthroline Lab Report

    1026 Words  | 5 Pages

    METHOD OF ESTIMATION: Iron (II) is quantitatively complexed with 1, 10- phenanthroline at pH 3 to 3.5 and forms orange-red color complex which is very stable. The intensity of color formed is directly proportional to the amount of iron in the sample therefore can be determined spectrophotometrically. MATERIALS AND METHODS: Instrumentation: • All absorbance measurements will be conducted using UV-VIS Spectrophotometer (Shimadzu, UV mini-1240, Japan) and 1 cm matched plastic cuvettes. • Weighing

  • Dioxins Research Paper

    2333 Words  | 10 Pages

    Dioxin is a large group of chemical compounds that are persistent environmental pollutants (POPs), which essentially comprise carbon, hydrogen, oxygen and chlorine atoms with similar structure. The toxicity of different dioxins is determined by amount of chlorine atoms and their positions in the dioxin molecule. To that, the most toxic dioxin has four chlorine atoms in positions 2, 3, 7 and 8, namely 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin, which is also usually known as TCDD or generically “dioxin”
