Name: Date of experiment: 04/02/12 Date of report: 04/03/12 Title: Oxidation – Reduction Activity Series Purpose: To determine relative oxidizing and reducing strengths of a series of metals and ions. Oxidation and reduction reaction occur simultaneously side by side. A reduction reaction occurs only if an oxidation reaction occurs and vise-versa. Electrons are given in oxidation while in reduction electrons are gained. Oxidizing agent is a chemical substance which has a large tendency to

YOUR NAME: Erin Alston‚ Kennedy Stuart‚ Amber Lamb and Stephonya Williams EXPERIMENT TITLE: Oxidation: Cyclohexanone from Cyclohexanol by Hypochlorite Oxidation and Adipic Acid from Cyclohexanone DATE: 4/18/2014 INTRODUCTION: In experiment 4‚ alcohol is oxidized to a ketone with household bleach. The product is then isolated by steam distillation and is extracted into the distillate with ether. After the removal of ether‚ it leaves the product cyclohexanone. In experiment 6‚ cyclohexanone is

Fermentation and affects it has on foods Fermentation is described as the transformative action of organisms and the metabolic change either anaerobic or aerobic processes converting energy needed to turn raw product to a finished fully fermented food. Fermenting food has become more popular because people are realizing that if it were not for fermenting as a collection of people we would be in trouble. Fermenting has been done for hundreds of years because if not for fermenting letting foods just

ABSTRACT The hypothesis which states that the simpler the nature of substrate‚ the faster the rate of cellular respiration of yeast was tested using the smith fermentation tube method. The experiment used six smith fermentation tubes‚ distilled water and sugar substrates. It composed of six set-ups which used 15ml of 10% yeast suspension‚ 15 ml distilled water and 15 ml of their assigned sugar substrate namely: starch‚ lactose‚ sucrose glucose and fructose respectively. Set-up six was the

Fermentation Fermentation is a natural process that has been going on in nature since before humans existed. For centuries we have been practicing food fermentation‚ knowingly or unknowingly. Every food culture in the world throughout history has been using fermentation in their food in some way. Bread making originated in Egypt 3500 years ago. Fermented drinks were being produced and consumed in Babylon(now Iraq) 7000 years ago. China is thought to be the birth place of fermented vegetables. A

of that substance by titrating the sample with a solution of a strong oxidizing agent. In this lab‚ a solution of KMnO4‚ an oxidizing agent‚ will be standardized by titration with a solution containing a known concentration of iron (II) ions‚ (Fe+). The concentration of oxalic acid solution will be determined by titration with the MnO4- solution that had been standardized first. The purpose of this lab is to standardize a solution of potassium permanganate by redox titration with a standard solution

1. Mechanism of oxidation process In an oxidation process of silicon that usually takes place at very high temperature (thermal oxidation)‚ silicon (Si) reacts with either water vapor (H20) or oxygen (O2) to form silicon dioxide‚SiO2 on the silicon surface. The reaction is represented by following equations: Dry oxidation: Si + O2 → SiO2 Wet oxidation: Si + 2H2O → SiO2 + 2H2 The oxidation process can be implemented through diffusion

How Carboxylic Acids and Alcohols React to Produce Esters: Esters and Ester Production: Esters are abundant and ever present‚ and are the chemical basis of almost all fatty acids and oils. Small esters are responsible for the aroma of fruits‚ perfumes and‚ by extension‚ wines and other alcohols. Esters are formed when a carboxylic acid and an alcohol chemically combine‚ losing a molecule of water in the process. Carboxylic acids are organic molecular compounds that form a homologous series
