Carboxylic acid and Alcohol. The product Ester is in equilibrium to the reactants acid and alcohol. Ester is responsible for the smell and aroma of different fruits. After using the Fisher reaction‚ a combination of techniques is used to separate the product. Introduction Esters are naturally occurring compounds that possess a distinctive odor. It is responsible for the smell of different fruits such as bananas and strawberries. Esters are most commonly from Carboxylic acids‚ and Alcohols. They have

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 titrant(known substance) from a burette‚ to a known

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
