Investigating the Kinetics of the reaction between Iodide ions and Peroxodisulphate (VI) ions By the use of an Iodine clock reaction I hope to obtain the length of time taken for Iodine ions (in potassium iodide) to react fully with Peroxodisulphate ions (in potassium Peroxodisulphate). I will do three sets of experiments changing first the concentration of iodide ions‚ then the concentration of Peroxodisulphate ions and finally the temperature of the solution in which the reaction is taking place. From these

Introductory Activity Heart Rate (pulse) Have the students find their heart pulse on the carotid artery of the neck. Use the index and middle finger to measure the pulse. Count the number of beats for 6 seconds and add a zero to the end of that number. This number represents the heart beats per minute. The heart pulse is located on either side of the wind pipe‚ next to the voice box. Allow the students to practice measuring their pulse to determine their resting heart rate. Explain that they need to

The Equilibrium Constant of an Ester Hydrolysis Reaction Jesus Flores March 30th‚ 2015 Abstract: This experiment was conducted in order to discover the Kc‚ equilibrium constant‚ of a hydrolysis reaction of an unknown ester #2‚ unknown acid‚ and alcohol #2 products. The first week consisted of creating the reaction mixtures in bottles‚ next was preparing a NaOH solution while neutralizing with KHP. The final week consisted of titrating the bottles with the NaOH solution prepared previously

Ashley Silva Lab 7: Three Stooges in Chemical Reactions Objective: The purpose of this lab is to experimentally determine the equilibrium constant‚ Kc ‚ for the following chemical reaction: Fe3+ (aq) + SCN-(aq) ↔FeSCN2+(aq) Background Information: A system is at equilibrium when the rate of the forward reaction is the same as the rate of the reverse reaction. There is no change in concentration for the reactants or products at chemical equilibrium. When the system is disturbed there

ERYTHROCYTE SEDIMENTATION RATE | -AND ITS VARIATION | | ABSTRACT: The Erythrocyte Sedimentation Rate (ESR)‚ also branded as sedimentation rate or Biernacki Reaction‚ is the rate at which red blood cells sediment in a time of 1 hour. To execute the test‚ anti-coagulated blood is positioned in an erect tube‚ known as a Westergren tube‚ and the rate at which the red blood cells fall is calculated and accounted in millimeters per hour (mm/h)

purpose of this experiment was to prepare the Grignard reagent methylmagnesium iodide and react it with benzoin to form the 3o alcohol 1‚2-diphenyl-1‚2-propanediol‚ through an addition reaction pathway. Introduction: Grignard reagents are alkyl or aryl-magnesium halides that act as the nucleophile in Grignard reactions‚ where ketones are reacted with the reagent‚ then treated with acid to produce an alcohol. In the case of this experiment‚ methylmagnesium iodide was created from methyl iodide and

Exchange rate development in Ethiopia Monetary Development The legal tender currency of Ethiopia was issued on 23 July 1945 by defining the monetary unit as the Ethiopia dollar (E$) with a value of 5.52 grains (equivalent to 0.355745 grams) of fine gold. The linkage with fine gold was in accord with the monetary system established by the Bretton Woods Agreement of 1944. For the five years following the proclamation of the national currency (1945–1950)‚ money supply of the country was determined
