spectrometry. We will do this by making 2‚ 4 a DNPH derivative and checking the melting points. Theory: By Using specific methods of compounds detection‚ we can match an unknown compound with a known compound because similar compounds will display similar characteristics. In this experiment‚ identifications of the unknown ketone was accomplished using thin layer chromatography‚ melting point‚ and NMR spectrometry. Thin layer chromatography is very quick but sensitive way of determining the components

an Unknown Compound Purpose: The purpose of this experiment was to separate a mixture of two or more unknown compounds and identify them based on their melting point and reactivity with an acid or a base. Compound studied/Reactions: The organic solvent used in this experiment was methyl t-butyl ether (MTBE‚ 2-methoxy-2-methylpropane). The unknown that dissolved in the MTBE‚ but was insoluble in water. MBTE is very volatile and flammable. It was determined in the experiment that the unknown was

Purpose: The purpose of this was to determine the concentration of sodium carbonate in an unknown sample by titration. The solution of hydrochloric acid was prepared and standardized using Na2CO3. Observations: Week 1: Standardizing hydrochloric acid using sodium carbonate with bromocresol green indicator Table 1: Titration of sodium carbonate using hydrochloric acid Trial | Mass of Na2CO3 (g) | Burette Reading (mL) | Final Volume of HCl (mL) | | | Initial | Final | | 1

and Report: Introduction: The experiment was conducted to find the unknown molarity of HCL. The unknown molarity of HCL was found by the use of the titration method and then comparing the results between the titrant and analyte HCL solutions. Molarity is a concentration unit‚ it is defined by the number of moles the total volume of the solution. This experiment included a process called titration‚ used to work out the unknown concentration of a known substance. The process of titration is adding

Goals The main goal of this project is to learn how to identify the properties of an unknown ionic compound. In order to do this successfully the group has to use a variety of methods and run several tests on the unknown compound. By doing this the group will be able to identify the different chemical and physical properties of the compound that will help obtain the identity of the specific compound given. The group will devise two syntheses of the compound‚ and compare them for cost effectiveness

The Tomb of the Unknown Soldier is a practice utilized throughout the world to memorialize soldiers who have died in modern wars without being identified. The first monument of this kind was the Tomb of Unknown Soldiers in Frederica‚ Denmark (1858)‚ which memorialized unknown soldiers who died in the First War of Schleswig. Another such Tomb of the Unknown Soldier is found in Philadelphia‚ Pennsylvania and was erected in 1866 to honor those soldiers who died during the American Civil War. The history
