Chemical tests and procedures were used to discover the identity and properties of an unknown compound, later confirming it with further testing and a synthesis reaction. To initially determine the unknown compound, flame and pH tests were conducted to narrow the range of possible identities. Once a hypothesis for the compound was formed, ion tests were performed to determine more properties of the previously unknown substance. To confirm the hypothesis, the compound was synthesized and ion tests were conducted. These results were compared with the initial ion tests of the unknown compounds. The flame and pH tests on known compounds and the unknown compound suggested the unknown substance to be magnesium chloride (MgCl2). After the synthesis…
To determine the identity of the unknown compound many tests were performed. These tested the pH, qualitative solubility, quantitative solubility, conductivity, anions present in the compound, and cations present in the compound. The results of each test can be found in Table Whatever. In the cation test, we used two tests, the flame test and the ammonium test, to determine the identity of the cation present in the unknown compound. We also performed these tests on known compounds to know how a…
parts. The main goal of the experiment is to identify the unknown compound the lab group was given. Along with this, the group is to discover the compounds many physical or chemical properties. Lastly, the group is supposed to create and preform two syntheses of the compound and see how they compare and contrast in different areas like costs effectiveness, safety, and potential yield of the compound. Through all of these different goals, the underlying key goal is to learn more about this…
unidentified compound that was discovered in a local landfill. The group was called in to help determine the chemical and physical properties of the compound so we can let the people of the town know so it can be taken care of properly with or without further precautions to be taken. Another goal of this project was to devise the synthesis of the unknown compound. Experimental Design In order to determine the correct identity of our unknown compound, we first started with a couple preliminary…
Compound Bow: Introduction Introduction Bows are tools or weapons used by archers and archery hunters to compete in competition and harvest wildlife for food and trophies. The compound bow in particular, is a mechanical tool/weapon that enhances the primitive technology originally created by man to enhance accuracy when hunting or shooting at a target. Compound bows can be used for hunting various types of game as well as used for competition shooting. People of most ages with practice and…
Since there are more than 50 million chemical compounds on Earth and even more being discovered or synthesized each year, it is increasingly difficult to identify compounds.1 However, with the help of physical and chemical properties of the atoms or molecules that make up a compound, identifying a chemical compound is not as daunting as it may seem. There are three main types of chemical compounds: metallic, covalent, and ionic compounds.2 In this experiment, however, the unknown compounds are…
Identifying an Unknown Compound Using Various Chemical Analysis Techniques Joshua Nash and Aquilla Young Abstract The introduction of this lab report exposes the reader to the different scientific concepts that are to be used such as melting point calculations, retention factors, and solubility in various aqueous solutions. The experimental provides the basics of using a melting point apparatus, determining solubility, and performing thin layer chromatography. In the results section the findings…
The goal of the lab was to identify an unlabeled compound found in the chemistry stockroom to be able to dispose of it properly. This lab demonstrated the process of identifying an unknown compound as well as synthesizing the compound. Identifying the compound consisted of performing various tests to detect the chemical and physical properties of the compound and comparing it to the list of possible compounds. The tests conducted were the solubility test which the compound fully dissolved in…
Identifying Unknown Substance. Examining the physical characteristics of the available compounds in the lab was how possible compounds were eliminated from any or further testing. Based on how the compounds physically looked, it was almost for certain that calcium chloride was the unknown compound. However, another compound was used to test as well (ammonium chloride) since relying only on physical characteristics alone would not allow for proper experimentation. The unknown ended up being…
The objective of Chapter 6: Compounds and Elements was to determine how to synthesize and decompose pure substances, distinguish the difference between compounds and elements, and to determine the difference between complete and incomplete reactions. Previous chapters that contained valuable background knowledge were Chapter 2: Mass Changes in Closed Systems and Chapter 5: The Separation of Mixtures. The Law of Conservation of Mass, which was tested in Chapter 2, proved to be vital in this…
