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

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

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

Purpose: To identify an unknown bacterial specimen using basic laboratory technique and biochemical tests. The unknown bacteria will be one of the following: Enterococcus faecalis‚ Staphylococcus saprophyticus‚ Escherichia coli‚ Enterobacter aerogenes‚ Proteus vulgaris‚ Salmonella [I assume typhimurium]‚ or Shigella [either flexneri or sonnei‚ we used both in our lab during the semester]. Procedure {and observations}: Observe bacterial colony morphology. {Colonies are large‚ beige or

identify a metal‚ each with varying amounts of accuracy. In order to test some of these methods‚ thermal expansion‚ density‚ and specific heat were used to identify two small metal rods. The overall purpose of this experiment was to identify an unknown metal using the three previously stated properties. This means that the percent error should be relatively low‚ meaning that there would be little difference between the values measured in our experiment and the true values of the metal. Density

Girl by Jamaica Kincaid Jamaica Kincaid relates the relationship between a mother and daughter in her poem‚ “Girl”. The poem is about how a mother prepares her daughter to become a woman. She gives her a litany of valuable lessons to shape her behavior and character according to what is acceptable to their culture.
