Oxidizing agent

observed for its ability to serve as a counterion for precipitation by preparing a copper (II) complex by reacting hydrated copper (II) sulfate with ammonium peroxodisulfate in the presence of pyridine. This same ability, coupled with its strong oxidizing ability allowed for stabilization of the unusual oxidation state of 2+ for silver which was observed by preparing an analogous silver (II) complex by reacting silver (I) nitrate with ammonium peroxodisulfate in the presence of pyridine.

CH 204 – Introduction to Chemical Practice Experiment 6 – The Copper Cycle Samuel Stewart* TA: Brad Hu October 27, 2017 This laboratory experiment is appropriately entitled “The Copper Cycle” because the sequence of reactions begins and ends with elemental copper metal. According to the Law of Conservation of Mass, since no copper is added or removed between the initial and final reactions; and assuming the reactions go to completion, the copper yield should match the amount originally

Multi-Step Synthesis of Benzilic Acid from Benzoin Abstract: The main purpose of this experiment was to convert a secondary alcohol to a ketone, utilizing a mild and selective oxidizing agent. In addition, this converted alpha diketone was then subjected to rearrangement to a carboxylate salt, then acidification, to produce an alpha-hydroxyacid. In this experiment, benzoin was used and converted into benzil, which was then used to synthesize benzillic acid. The yields were not ideal: .081g of benzil-

chemistry involving quantitative analysis Aim: To investigate if changing temperature will effect the concentration of NaOCI- in the bleach inside Janola. Introduction: The active ingredient in most chlorine bleaches is sodium hypochlorite, NaOCl. The oxidizing action of hypochlorite ion, OCl-, kills germs and also decolorizes many stains and dyes. I will determine the concentration of the active ingredient in household bleach; Hypochlorite Ion (OCI-). I will do this using a titrimetric analysis in which

nitrate was reduced by sodium borohydride, with the aid of sodium citrate to manipulate the sizing of silver nanoparticles. Without sodium citrate, bulky, ununiformed precipitates will begin to form without control. Hydrogen peroxide served as an oxidizing agent to balance out the reduction of sodium borohydride and oxidation of hydrogen peroxide. Hydrogen peroxide & sodium borohydride shall not react particularly in this experiment. Typically, when those two reagents react, H2 gas will form. There was

Bleach Oxidation of 9-Hydroxyfluorene The purpose of this experiment was to oxidize an alcohol (9-hydroxyfluorene) to a ketone (9-fluorenone) using aqueous sodium hypochlorite (bleach) as the oxidizing agent, while introducing techniques used in microscale experiments. Reaction: Results 1. Recrystallized Product Yield Product yield = (actual yield/theoretical yield) x 100% 3mL 9-hydroxyfluorene x (1mL/1000mL) x (0.09 mol/L) = 2.7 x 10-4 moles 0.05g 9-fluorenone / (180.20g/mol) = 2.77 x 10-4

Water Assignment: Part 2 1: What is acid rain? What type of chemical reactions are involved in it’s production? Why is acid rain harmful to the environment. Acid rain is any form of precipitation with acidic components such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet and dry forms. Acid rain is a result of when sulfur dioxide and nitrogen oxides are emitted into the atmosphere and are transported by wind and air currents. (What is Acid Rain? (2017, March 01).

open chain and closed ring(orcyclic), strutures. sugars that can be oxidised by mild oxidising agents are called reducing sugars because oxidising agent is reduced in the reaaction. A non reducing sugar is not oxidised by oxidising agent . All common monosaccrides are reducing sugars. there are several test forr sugars which are based on composition or specific group. Hence sucrose is not a reducing agent due to bonding of oxygen with carbon to form glycosidic bonds between monosacrrides. Therefore

Selective oxidation of 2-naphthol to 2-hydroxy-1,4-naphthoquinone with hydrogen peroxide catalyzed by 5,10,15, 20-tetrakis(p- sulfonato-phenyl)porphinatomanganese(III) chloride in aqueous solution.
