You have recently reached out to our firm Nittany Chemical Analysis to assist you in assigning the correct empirical formula for Manganese ( ) Chloride. On the 14th of September 2015, we carried out an experiment and we were able to accurately determine that manganese had an oxidation number of III. From this finding we are confident that the empirical formula for the compound in question is Manganese (III) Chloride. Throughout the entire course of this letter, we will further explain our techniques and procedures that we used for this experiment. Also, for transparency purposes, we have included the results that were obtained from the experiment.
In carrying out the experiment, we first had to measure out a 1.1 (g) sample of manganese then add it to a crucible of known mass (39.6 g). To …show more content…
This result was confirmed also by a credible source, http://chemwiki.ucdavis.edu/ . Manganese is widely known to have common oxidation states of +2, +3, +4 and +7, which means that our experimental finding is not off the scale. However, as with any well done experiment, there are always possible sources of error. For instance, the experiment was not conducted under sterile conditions, which could have led to contamination. Another point to note was that we used metal tongs that were, somewhat, rusting and this could have also contributed to contamination. Most of our calculated results were rounded off to two or three significant figures, which means that the values recorded were either slightly greater or smaller than the actual values. For a better experiment next time, we strongly believe that the conditions under which we conduct the experiment be sterile. As for the calculations, we should consider using at least four significant figures so as to get more accurate results. It was a
