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.

Seekers of wisdom and truth, however diverted in two completely different directions, some likely intend either to adopt an algorithm or an equation suggested by any sorts of the mathematics alike engaging in an effort to unveil complexity of the unknowns to the future, or tricky concepts on the some certain subjects of what issues the foremost complicated and abstract, following draws them into the realm of being the comprehensible and the plausible thus be best understood by entire human society. In his view, Descartes believes that even thinking that an individual does not exist implies that he is a thinking being therefore he exists. This argument did not convince me at all. Descartes held that some ideas innate ideas come from God where others ideas come from sensory experience as well as are created by the imagination. For Rene Descartes he believed that knowledge of eternal truths mathematics and the epistemological and metaphysical foundations of the sciences could be attained by reason alone, without the need for any sensory experience. The spirit that gave birth to modern science is the same spirit that led to the initiation of modern philosophy. He is considered one of the first philosophers to explore human as more than flesh and blood Weate, 1998, pp.

Descartes argued that the idea of god should be coming from within him since he cannot experience god himself directly or find any perfection in himself. . That they are not just objects of possession, but have free will. History is not just the compilation of the past that is being recorded solely without any research and discussion, but after the facts are being interpreted and analysed into something significant, that is what we called history. How would I know that a robot is making my choices and decisions for me? Since people think, they too exist, just like the Supreme Being Descartes, 2012. Therefore, Descartes does not explain any phenomenon, but only states the obvious idea that everybody can identify. Doubts are responsible for shaping our thinking because we do not have to approve every data get as well as we do not have to disregard them, but should analyze them through critical thinking in order to construct a conscious being.

For instance, in our dreams as we sleep, we might dream of an apple or oranges. With this he switches his comparison of himself, instead offering the image of Archimedes, able to move the entire planet with just one fixed point. Unless by chance, I remember that, when looking from a window and saying I see men who pass in the street, I really do not see them, but infer that what I see is a man, just as I say that I see wax. Get downing in Meditation Two. In the sixth and final meditation he talks about the mind and the body. .
