Gravimetric analysis is a method of quantitative chemical analysis in which the mass of a compound is used to determine its quantity. This technique is particularly useful for determining the concentration of a soluble chloride, such as sodium chloride (common table salt). In this essay, we will discuss the general principles of gravimetric analysis and the specific steps involved in performing a gravimetric analysis of a soluble chloride.
The basic principle behind gravimetric analysis is the measurement of mass. In order to determine the mass of a compound, it must first be isolated from the rest of the sample. This is typically done through a process called precipitation, in which the compound is transformed into a solid that can be easily separated and weighed.
The specific steps involved in a gravimetric analysis of a soluble chloride depend on the particular chloride being analyzed and the desired end result. However, there are some general steps that are followed in most gravimetric analyses.
First, the sample is prepared by dissolving it in a suitable solvent. The solvent should be chosen based on the solubility of the compound being analyzed and the desired end result. For example, water may be used as a solvent for a soluble chloride if the goal is to determine the mass of the chloride.
Next, the precipitating reagent is added to the sample. This reagent is chosen based on the solubility of the compound being analyzed and the desired end result. For example, a soluble chloride may be precipitated as a silver chloride by adding a silver nitrate solution to the sample.
Once the precipitate has formed, it is allowed to settle to the bottom of the container. The supernatant liquid is then carefully decanted, leaving the precipitate behind. The precipitate is then washed with a solvent to remove any impurities that may have been present in the sample.
Finally, the precipitate is dried and weighed to determine its mass. This mass can then be used to calculate the concentration of the soluble chloride in the original sample.
In summary, gravimetric analysis is a powerful tool for determining the concentration of a soluble chloride. By following the steps outlined above, it is possible to accurately and precisely determine the mass of a compound, which can be used to calculate its concentration.
Case Study: Scam of the Century
BP appeared to be more focused making profits and expanding their business without considering the affect on stakeholders. For instance, there was no record of account transactions at the Fidelity Investment Spartan Fund, yet Madoff had listed that there were such transactions that took place in that bank; that was a plain lie! Buying stocks is a high-risk venture, and the less information and control an investor has, the less secure they are in their financial stability, which is not consistent with the accepted business ethics. Each coupon was good for one stamp in any of the affiliated countries; this allowed the mail services to continue operations smoothly despite the instability of most European currencies at the time. To begin, one must not be fooled by an extravagant client list. However, external influences and selfish motivations can alter this natural instinct. It is said that case should be read two times.
Bernie Madoff
Comparison of Buffet to Madoff Before his infamous investment fraud, Bernie Madoff was seen as a business person similar to Buffet. The SEC went to investigate Madoff in his building on the 18th and 19th floor but missed a whole 17th floor where the scam was mainly doing its operations. Thus, if clients leave the hedge fund industry by the droves because of a lack of trust in hedge funds, then the industry may be forced to act. Similar to Buffet, he also promised large returns, was reserved in disclosing financial information to the investors, and strived for maximum control of financial operations Carlson, 2019. On the other hand, other accounting bodies also might not went beyond their comfort zone to circle out how the fraudsters are using the loopholes to implement their fraud and misappropriate public money.
Case Study #1
Whereas, the opportunities and threats are generally related from external environment of organization. Even, the competitive parity is not desired position, but the company should not lose its valuable resources, even they are common. He should have used the results of his independent audit to build his case and support the one he already had with SEC. For example, Walter Noel, a US fund manager of The Fairfield Greenwich Group, experienced the largest loss of money. This is relevant to year 12 students because it shows the high life that these people lived every day and while it was great for a short period of time, when it all came crashing down these people served jail sentences, lost all of their money and had no hope of working in that industry again.
