The kinetics of the Harcourt-Essen Reaction (Hydrogen peroxide variation) Aims: To find the order of the reaction with respect to the Hydrogen Peroxide (H2O2)‚ Potassium Iodide (KI) and the Sulphuric Acid (H2SO4) by the use of an Iodine clock reaction. Calculate the rate constant‚ mechanism and equation Find the effects of temperature on the rate of reaction The effects of a catalyst on the rate of reaction Find the activation enthalpy (Ea) of the reaction‚ with and without a catalyst Background:

PurposeIn this experiment‚ sodium hypochlorite (NaOCl) in acetic acid mixture was used to oxidize emdo-borneol (an alcohol) to camphor (a ketone). The product would then be purified by sublimation and then be analyzed by Infrared spectroscopy and melting point test. Procedure and ObservationsPlease refer to the lab manual and the carbon copy attached. Data and CalculationsWeight of endo-borneol = 0.2013gNo of moles of endo-borneol = 0.2013g/154.25g mol-1 = 1. 305mmolSince one mole of endo-borneol

MSG or monosodium glutamate is a sodium salt of glutamic acid which can be naturally found in many common foods that are rich in protein content such as dairy products‚ meat‚ vegetable and mother’s milk. In fact‚ our own bodies do produce glutamic acid via Krebs cycle during metabolizing food. Glutamate is the most abundant naturally occurring non-essential amino acid (Ninomiya‚ 1998) and it is a very common part of our diet. In the food industry‚ MSG is widely used as a flavor enhancer. It is responsible

number of moles of HCl reacted with the NaOH is 0.00216 moles‚ which is less than Gaviscon. The number of moles of NaOH that were added from the burette is 0.00327 moles (1 tablet of Gaviscon). However‚ for Quick-eze‚ the number of moles is 0.00216 moles (1 tablet). This means the average volume of the NaOH have affected the number of moles as the concentration of the sodium hydroxide is 0.1M. This means that if less NaOH was required to neutralise the acid‚ the number of moles of HCl neutralized by

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

Introduction In this coursework I will be talking about the experiments‚ which I have done over two weeks. This gave different results by using different concentrations of hydrochloric acids (HCl) and indigestion relief tablet. I will also mention the time which was taken in the experiment‚ to see how fast the hydrochloric acid took with indigestion tablet with different concentrations. Indigestion tablets are alkali and they are used for to neutralise the excess acid in the stomach. Indigestion

My Reaction Paper This is my reaction paper on a movie that I watched entitled “The Wizards Of Waverly Place: The Movie”. Wizards of Waverly Place: The Movie follows the Russo family as they embark on a vacation to the Caribbean resort where Jerry and Theresa first met. Alex‚ upset that she was forced to accompany her family on the trip‚ conjures a spell that erases her parents’ fateful first meeting and puts the Russo family’s very existence in peril. In order to reverse the spell‚ Alex
