Date of experiment : 7th August 2012 Venue: ME204 INTRODUCTION Chemical reactions are regularly categorized into 3 types: oxidation-reduction (redox reaction)‚ precipitation (double displacement) and acid-base reaction (double displacement) Type 1: Oxidation-Reduction Reactions Oxidation-reduction processes include the movements of electrons form oxidants to reductants‚ which lead to increases in oxidation number for oxidised species and decreases in oxidation

Reactions Lab Objectives: 1. To examine a variety of reactions including precipitation‚ acid-base‚ gas forming‚ and oxidation-reduction reactions. 2. To identify the products formed in these reactions and summarize the chemical changes in terms of balanced chemical equations and net ionic equations. 3. To identify the species being oxidized and reduced in oxidation-reduction reactions and determine which species is the oxidizing agent and the reducing agent. Chemical equations represent what occurs

The Action of Naturally Occurring Toxins and Medicines It is important to classify toxins and medicines (drugs) in order to understanding the mechanism and function of each one of them. By doing so‚ it is also possible to increase their values by altering their mechanism (e.g. converting toxins to drugs) to cure diseases and improve human health. Therefore in this review‚ the mode of action of several toxins and drugs as well as their effects on human body will be discussed. 1. Cobratoxin Cobratoxin

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

dehydration. Euvolamia is the term used to describe a state of normal body fluid (Welch 2010). Approximately 60 percent of a male’s body weight and 52 percent of a female’s body weight is fluid‚ which consists mostly of water and electrolytes. A reduction of only 5 percent in this fluid would result in a patient developing thirst and would be considered mild dehydration. 8-10 percent would cause hypertension‚ tachycardia‚ weak pulse‚ confusion and a decrease in urine output. 10-15 percent would be

DETERMINATION OF VITAMIN C CONTENT IN COMMERCIAL (CENOVIS) TABLET ABSTRACT In this experiment‚ the vitamin C content of a commercial tablet is determined and compared with the manufacturers’ specification. Vitamin C is water-soluble and is an enantiomer of ascorbic acid. (Commercial vitamin C is often a mixture of ascorbic acid and other ascorbates.) Ascorbic acid‚ C6H8O6‚ is a reducing agent that reacts rapidly with iodine (I2). As the iodine is added during the titration‚ the ascorbic acid is
