    of substances. The inorganic substances are split-up into two types of charged particles one of which is positively charged and the other is negatively charged. The charged particles are called ions or radicals. The positively charged ions are called cation or basic radical. The negatively charged ion is called anion or acid radical. In the qualitative analysis of an inorganic substance number of tests are carried out in order to discover the acidic and basic radical present in it. A test is

    Exercise 14: Qualitative Anion Tests PURPOSE: The purpose of this experiment is to identify some commonly occurring anions & to study some of the reactions used for their identification. PROCEDURE: You must first determine to which of the three groups the various anions belong. Since no two people observe the same event in exactly the same way it is important to also conduct specific confirmation tests on the known samples of each anion. This information will help identify the anion

    reaction will occur. Polar protic solvents typically favor SN1 reactions. This is because the SN1 mechanism is carried out in two steps and the polar protic solvent produces both a cation and an anion which are capable of stabilizing the charges on the ions formed during the reaction. Because an SN2 reaction occurs in one step‚ this is unfavorable; however‚ the SN2 reactions tend to favor polar aprotic solvents. Another factor affecting the type of substitution reaction is the nature of the leaving group

    Analysis of Commercial Bleach Lab I. Purpose In this experiment‚ the amount of sodium hypochlorite in a commercial bleach will be determined by reacting it with sodium thiosulfate in the presence of iodide ions and starch. A solution of sodium thiosulfate of known concentration will be added to the bleach using a buret in a titration procedure. The disappearance of the dark blue color of the starch-iodine complex will signal the end point. II. Procedures Pre-Lab Questions 1. What is

    the based-catalyzed halogenation of the ketone that forms a trihalo ketone. First‚ the bleach is transformed into chlorine and hydroxide ions through the following reaction: Then‚ the hydroxyl is able to attack the rather acidic (pKa ~ 20) α-hydrogen of the ketone. This acidity is due to the stability of the resonance structures of the corresponding enolate ion that forms upon dissociation. When the hydroxide is able to subtract a hydrogen atom‚ a carbanion is formed. This carbanion is a very strong
