Purpose Use a standardized potassium permanganate solution to analyze an unknown iron solution by using redox titration. Theory Reduction-oxidation titration is an analytical method based on electrons transferring between an oxidizing agent and a reducing agent in solutions. Chemical analysis can be built on Redox titration if four criteria are met: a) The reaction is completed in a thermodynamically spontaneous condition. b) The reaction is fast enough to give an operational result instantly

IntroductionA dehydration reaction of an alcohol results in an alkene. This type of reaction requires an alcohol‚ an acid catalyst and heat. Generally strong concentrated acids‚ like sulfuric acid and phosphoric acid‚ are used as the acid catalyst.The acid catalyst protonates the alcohol‚ to make a much better leaving group. Weakest bases make the best leaving groups‚ so once the alcohol is protonated the leaving group leaves and produces in a carbocation and water. In order to form the double bond

Purpose: Cells produce toxic wastes‚ in this experiment hydrogen peroxide‚ and without some sort of molecule to break it down the cell will die‚ along with the organism itself. However with the aid of an enzyme‚ catalase‚ hydrogen peroxide is able to be broken down into an intermediate and thereafter harmless substances water and oxygen. The goal of this lab is to measure the reaction rate of this process in different substances such as a liver‚ a vegetable‚ and breast tissue. By using variables

Euripides’ Medea and Seneca’s Medea are the two surviving ancient tragedies of Medea. Both versions are drastically different and contrast in several aspects. Euripides portrays Medea as more human. She is the epitome of the oppressed housewife and only after her suffering is she capable of the crimes she committed. Seneca’s Medea is even more vengeful than Euripides’ and she is angry from the very beginning. Seneca’s version also portrays Medea as a vengeful sorceress whereas in Euripides’ version
