Using the Iodine clock method to find the order of a reaction Introduction When peroxodisulfate (VI) ions and iodide ions react together in solution they form sulfate (VI) ions and iodide. This reaction is shown below: S2O82-aq+ 2I-aq SO42-aq+ I2(aq) The reactants and the sulfate (VI) ions are colourless however the Iodine is a yellow/brown colour. This allows you to measure the progress of the reaction through the colour change when the iodine is produced. In order to determine the order of

Purpose: This experiment is used to perform a series of synthesis reactions that convert aluminum foil to alum. Alum is used in cooking‚ to treat wastewater‚ and is used in common deodorant. In this lab a series of four reactions will occur to yield alum. Calculations: Aluminum foil: 0.5035 grams Alum & Watch Glass: 21.7691 grams Watch Glass: 15.1560 grams Alum: 6.6131 gram Theoretical Yield of Alum: 2Al(s) + 2KOH(aq) + 4H2SO4 + 22H20 -> 3H2(g) + 2KAl(SO4)2 + 12H2O(s) 0.5035gAl

What is the scientific method ‚and how is the theory applied to fingerprint analysis? The complete friction ridge identification process involves using the "identification philosophy and scientific methodology" in determining whether or not an "unknown friction ridge impression"(herein‚ called latent) came from the same source as a "known inked print (herein called print)to the exclusion of all others. (1) David Ashbaugh refers to this identification process as‚ "a guide of how friction ridge quantative-qualititive

Scientific method is an epistemological system used by the scientists to investigate natural phenomena‚ developing new knowledge or correcting preceding knowledge (Jennings‚ 2008:5). It is considered the best objective framework to construct an accurate representation of the world‚ it include ideas‚ procedures‚ rules‚ techniques and modes which exist in theoretical research‚ applied research‚ development and promotion of scientific activities. This essay aim to prove that although the scientific

Laboratory #1 Introduction to Laboratory Techniques Sean Pence Jackie Butler September 6‚ 2012 September 13‚ 2012 Abstract: This lab contains four different experiments. All four experiments focus on proper laboratory techniques. The reasoning behind this lab was to become familiar with lab equipment‚ the proper usage of lab equipment‚ and how to correctly take data and notes. The first experiment of this lab was to determine the volume of water in various types of equipment. The second experiment was to

What are the main features of Taylor’s approach to ‘Scientific Management” and what criticisms have been made of it? Do firms use scientific management today? Frederick Winslow Talyor developed a theory called the Scientific Management. It is a theory of management that analyse and improve work process‚ aiming to increase labour productivity. Scientific management methods are used to optimize productivity and simplifying the jobs so that workers could be trained to perform their task in one “best”

the poems ‘’Singh Song!’’ and ‘’Checking Out Me History’’‚ both personas show a strong link to their cultural heritage through both the content of the poems and the use of nonstandard English to emphasise their accent. The speaker in ‘’Checking out Me History’’ seems to feel irritated that he has been ‘’blind[ed]’’ to his own roots and cultural background‚ using simple rhyme to emphasise the silliness of the white history he’s been taught rather than his own. Whereas in ‘’Singh Song!’’ the individual
