Discussion For the first part of the experiment, a solubility test was conducted on all compounds. Because they were all ionic, every known compound naturally dissolved in water, and conducted electricity. As the next determining factor in the process to identify the unknown substance, the compounds were tested in acetone. As seen in table 2, only one compound, Ca(NO3)2 was found to be soluble in this solvent. Because the unknown solid was insoluble in acetone, Ca(NO3)2 was then eliminated as a possible inorganic compound. The flame test did not help to eliminate any possibilities for the unknown, because each flame turned orange after being dipped in the different solutions. However, as a final qualitative test, the pH test further narrowed …show more content…
The formation of a precipitate implied that the unknown compound had to have an insoluble ion, and the findings implied that the unknown compound was magnesium sulfate. The goal of the experiment was accomplished, and can be further related to the research connections as a whole. The identification of compounds through these experimental tests can be exceedingly important in the protection of the world’s water sources. These same tests can be further applied to pollutants outside of the lab to protect our ecosystems and populations, and identify hazards before they …show more content…
Many issues today are caused by pollution or contamination through inorganic compounds so it is imperative that scientists and researchers known how to physically and chemically identify these substances. The testing of inorganic substances to determine the chemical makeup is present in many different types of research. Monthon Thanutamoayong is a scientific researcher who focused on the identification of inorganic pollutants in drinking water through nanofiltration. Through this type of testing, the rejection of certain organic and inorganic compounds is described regarding their size exclusion and electrostatic effect. (Thanutamoayong, 2002). Through his experiment, he completed analysis tests using UV light and absorption as a means of identifying certain compounds. His results show that the average composition of compounds in drinking water is mainly organic molecules and anions, with a small fraction being cations. His research proved the objective that many times the identification of an inorganic solute is dependent upon on the molecular size as well as molecular charge of target solutes, because the membranes normally have charged properties, such as negative, positive or even neutral, in different pH condition. (Thanutamoayong, 2002) Through these means of identification the composition of pollutants in
