  • Scientific Method Case Study

    in the chemistry lab, the chemicals sodium chloride, in both chip and powdered form, and hydrochloric acid. Michael decides to mix the two substances by pouring the hydrochloric acid on the sodium hydroxide in both states chip and powder form. Michael does not have an aim or reason for doing this so his intentions are unknown. Michael gives a possible outcome or hypothesis that as soon as the hydrochloric acid is added the chips of sodium chloride would react instantaneously and quick because of…

  • Hydrochlorimetric Purification Lab Report Conclusion

    Starting out, there was a mixture of an unknown acid, base, and neutral component. Just like the process outlined in the introduction, a solvent would be added to the solution containing the acid, base, and neutral unknown mixture. This solvent must have specific characteristics regarding solubility such that it dissolves the substance desired to be extracted while not dissolving or dissolving in only small portions the other substance not wanted purified out. It should also be easy to separate…

  • Essay On Titration

    Titration is used to determine the equivalence point of a reaction, or the point when the moles of acid are equal to the moles of base in a mixture. Titration is used to determine the concentration of an unknown solution by using an already known solution. This process is important because it is commonly in the medical field. For example, pharmacists use titration in the creation of drugs. In addition, doctors also titration when determining the concentration necessary to give their patients of…

  • Solar Cells Advantages And Disadvantages

    cells There are 3 main types of commercially available cells: 3.1.1Mono crystalline Silicon PV& Polycrystalline Silicon PV The occupational health issues are associated to chemical burns and inhalation of fumes from hydro fluoric acid (HF) and other solutions of acids (e.g., HNO3) and alkalis (e.g., NaOH) used for cleaning wafers ,removing complete oxide layer, and cleaning the reactor. Performing the slicing of wafers also results in solid waste for example (e.g., small pieces of…

  • Synthesis Of Aspirin Essay

    aspirin Aspirin, also known as acetylsalicylic acid, is an aromatic compound containing both a carboxylic acid functional group and an ester functional group. Aspirin, being a monoprotic weak acid, is only slightly soluble in water and it can be prepared by reacting salicylic acid and acetic anhydride in the presence of an acid catalyst. 1.2: History of aspirin Aspirin was first produced about 110 years ago but the natural form, salicylic acid, found in plants (i.e. the willow and myrtle)…

  • Effect Of Binder And Plasticizers On Pore Size

    CHAPTER 2 LITERATURE REVIEW 2.1 Effect of Binder and Plasticizers on the Gel Viscosity, Membrane Morphology and Pore Size According to M.R. Othman [7] the result of addition of PVA in Boehmite sol during peptization on the viscosity, coating time, pore size and BET surface area is presented in Table I,II,III, and IV. PVA was prepared by dissolving 2, 4, 6 and 8g of PVA powder into 100mL de-ionized distilled water. PVA with different concentration in the sol give a of characteristics viscosity…

  • Volumetric Analysis Lab Report Conclusion

    The two main purposes of the lab were to determine the percent by mass of acetic acid in vinegar and to determine the molar concentration of a strong acid. In both parts of the experiment a volumetric analysis was used. This is primarily the aid of volumetric glassware in order to determine specific measurements and calculations. Potassium hydrogen phthalate was used as the primary acid standard to determine the molar concentration of the sodium hydroxide solution in part one of the experiment.…

  • Methyl Methacrylate: A Case Study

    Styrene (St, 99%) and methyl methacrylate (MMA, 99%) were obtained from Aldrich company. These monomers were first dried over calcium hydride, were purified by being passed through a column of basic alumina, and were distilled under reduced pressure. Ethyl 2-bromoisobutyrate (EBIB, 98%), copper (I) bromide (CuBr, 99%), copper (I) chloride (CuCl, 99%), and other chemical reagents were procured from Aldrich company and used as received. N-methylbis[2-(dodecylthio)ethyl]amine (SNS) was synthesized…

  • Reaction Between Sodium And Sodium Hydroxide

    is a neutralization reaction. A neutralization reaction is a chemical reaction in which an acid and a base react to form an ionic compound (a salt) and water; the resulting pH is closer to 7. The general chemical equation for a neutralization reaction is: Acid + Base Water + Ionic Compound This can also be considered as a double displacement reaction. However, since the reacts are an acid (carbonic acid) and a base (sodium hydroxide) and the products are a salt (sodium carbonate) and water…
