CHEM RESEARCH TASK 1. INDICATORS Identify and describe some everyday uses of indicators including the testing of soil acidity/basicity. • Indicators are used regularly in chemical laboratories during chemical reactions. One important use is to determine the end point of a titration when an acid reacts with an alkali. The reactants and products of such a reaction are colourless so an indicator is a useful way to visually determine when the reaction is complete. Chemists also need to monitor

In the lab‚ the purpose was to standardize a KMnO4 solution than using it to evaluate how close a H2O2’s concentration was to its labeled concentration. In this lab‚ it was decided to compare the concentration of new Publix brand hydrogen peroxide to an old sample of the same solution. From the data collected in the first part by titrating a solution of FeSO4*7H2O with the KMnO4 solution‚ it was determined that the concentration was .028M MnO4-. This was able to be done because a known amount of

Lab Assessment Questions & Answers 1. Define why change control management is relevant to security operations in an organization. Change control is a precision arrangement of managing every change made to a system. This is to ensure that no unneeded changes are done‚ that every change is documented‚ and that no service is disrupted unless absolutely necessary‚ and that all resources efficiently used. 2. What type of access control system uses security labels? A LBA C Label Base Access

An astronomer has a goal to discover and understand the nature of objects in our universe. Astronomers analyze and interpret the information obtained in order to make accurate models of these objects using instruments that collect‚ record‚ disperse and magnify the light that celestial objects give off. In this laboratory I learned how to measure the altitudes of stars using a quadrant. A quadrant is a quarter of a circle that has been divided into 90 degrees. I also learned how to find the angular

4’33”‚ a brief introduction to John Cage’s life is mandatory. Born in 1912‚ it can be deduced that most of Cage’s creative thoughts originated from his father‚ who invented the submarine that held the world’s record of staying underneath water (Nicholls 4). At a young age‚ Cage learned piano from his aunt who exposed him to music of the 19th Century and laid his foundation in music theory (Haskins 19-20). Despite being a top student‚ Cage dropped out of college after realizing that the education system

Introduction Methyl Salicylate has been used for a long time for its pleasant odour and flavour. The objective of this experiment was to carry an organic synthesis; the preparation of salicylic acid from methyl salicylate. To do an organic synthesis‚ it is needed to chemically modify the molecules of another compound to end up with the desire compound. Methyl salicylate is the major constituent of wintergreen oil‚ which is why it was used in this experiment as the starting material. The new technique
