Investigating the effects of changing concentration: iodine clock reaction. Abstract This is an experiment to show the Iodine Clock Reaction. To create a chemical reaction to see how long it takes for solution to change to a dark blue Color. When changing the concentration of the iodide (K1) and adding distill water to make it up to 5cm³ each time. This is to see if the reaction takes less with less concentration or faster with more concentration added to the peroxodisulphatee. So with the solution

Analysis “The Ormolu Clock” is a short story written by Muriel Spark‚ who is considered to be one of the 50 greatest British writers since 1945. Dame Muriel is a poet‚ writer of fiction and literary criticism‚ and biographer – went on to win most of the literary awards going‚ was never out of print‚ and was at the top of her profession‚ internationally‚ for more than half a century. The story under discussion begins with the description of two hotels standing side by side and separated by a

Chemical Kinetics: The Iodine-Clock Reaction: S2O82−(aq) + 2 I−(aq) → I2(aq) + 2 SO42−(aq) To measure the rate of this reaction we must measure the rate of concentration change of one of the reactants or products. Here‚ it is convenient to carry out a clock reaction involving the product I2. To do this‚ you will include (to the reacting S2O82− and I−) i) a small (but accurately known) amount of sodium thiosulfate‚ Na2S2O3‚ and ii) some starch indicator. The added Na2S2O3 does not interfere with

which non-rational or magical phenomena play a significant part’ (Manlove‚ 1975‚ 1). Following this definition‚ The Cuckoo clock would be classified as a fantasy by several elements in the story. To begin with‚ the story is based on the classic idea of a child communicating with animals or objects. In this case‚ that object would be the wooden cuckoo coming out of the clock. This idea itself is quite a common subject matter for children’s literature. For example in Little Princess‚ the little girl

Prince that a ruler should behave as both a fox and a lion‚ being both loved and feared. There are clever rulers who were strategic‚ courageous rulers who were effective‚ and successful rulers who possessed both qualities. Elizabeth I of England and Henery IV of France were two great rulers from Europe that were able to personify Machiavelli ’s advice. Elizabeth I of England was able to act as a "fox" by preventing England from being torn apart over matters of religion. By repealing The Catholic

most effective‚ this aim will be carried out as an iodine clock reaction. The goal of this aim is to find out what catalyst is best to make this reaction occur at the fastest rate. 3. Determine the effects of the presence of ethanol on the rate equation. It is known that ethanol effects hydrogen peroxide and therefore it has an effect on the rate equation. This aim will find out the effect of ethanol by carrying out the iodine clock reaction with and without ethanol present and the results
