moles/1000 mL = .0005 moles/10 mL = moles of hydroxylammonium chloride Ratio of Fe+2 to NH3OH+ = 2:1 2e- + 2Fe+3 --> 2Fe+2 so transfer of 2 electrons NH3OH+ --> something + 2e- Oxidation number of N in NH3OH+ is -1‚ therefore the oxidation number for N on the product side must be +1 because it gains 2 electrons. N2O has an oxidation number of +1 for N‚ so that would work. Data:Equation 1: NH3OH+ + 2Fe+3 --> something + 2Fe+2 Equation 2: 8H+ + 5Fe+2 + MnO4- --> 5Fe+3 + Mn+2 + 4H2O Equation 3: 6H+ +

Benzil is produced in the first step of this experiment’s multistep synthesis through the oxidation of benzoin. In order to produce the desired o-diketone‚ the alcohol on benzoin must be oxidized. Nitric acid was the oxidizing agent used in this experiment. As a result‚ the alcohol group on benzoin acted as the nucleophile and attacked the electrophilic nitrogen of nitric acid. As this step forms oxonium‚ excess water in the system deprotonated the oxonium to restore the neutral charge on oxygen

using Potassium permanganate which is a strong oxidizing agent‚ with unknown sample dissolved in deionized water. The result of the experiment was a 99.5% purity for the anhydrous iron (II) ammonium sulfate. Introduction: In this experiment‚ oxidation/reduction (or redox) will be used in the titration analysis of an iron compound. We will use potassium permanganate‚ KMnO4‚ as the titrant in the analysis of an unknown sample containing iron to determine the percent iron by mass in the sample

This experiment was a Landolt Iodine clock reaction - Oxidation of Bisulphite by Iodate. It involved conducting three measured experiments. The first variable tested was concencentration. This was tested by conducting two experiments‚ each varying the concentration of either the NaHSO3 or KIO3. The varying of NaHSO3 involved using 0.1 Molar of KIO3 against decreasing concentrations of NaHSO3 (0.25 M‚ 0.125 M‚ 0.0625 M and 0.03125 M). When decreasing the concentration of KIO3‚ 0.25 M of NaHSO3 was

Module 16 Notes Reduction/Oxidation Reactions • Oxidation number: The charge that an atom in a molecule would develop if the most electronegative atoms in the molecule took the shared electrons from the less electronegative atoms. • Oxidation numbers are not real; they are only based on assumptions. They are useful bookkeeping tools though‚ and can help us keep track of electrons during a reaction. • The sum of all oxidation numbers in a molecule must equal the charge of that molecule. • Rules

between the molecules in a chemical reaction provides the kinetic energy needed to break the necessary bonds so that new bonds can be formed. Thus‚ increasing the concentration of the anode‚ zinc sulfate‚ will increases the rate of reaction for oxidation because there are more zinc ions in the new concentration‚ which would also increase the collision between molecules. This will eventually allow an increase in the transferring rate of electrons to the cathode‚ as there are certainly
