Some scholars use quantitative methods in their study of the causes of conflict. Explain these methods and identify their strengths and weaknesses. The assignment should be 800-1000 words (excluding references). Assessment: ability to focus on and answer the question set; command of the material (including the wider academic debate); analysis and critical discussion around an argument or approach; logical structure of arguments; use of academic language; editing; introduction and conclusion; and

Acid and Base Titrations: Preparing Standardized Solutions Introduction: This experiment focuses on titrations of acids and bases. A titration depends on addition of a known volume of solution and is a type of volumetric analysis. Many titrations involve either acid-base reactions or oxidation-reduction reactions. In this experiment we do one of each. We monitor the pH of the reaction with the use of a color indicator. We also learn about the standardization of bases (NaOH) and acids (HCl) which

the complexometric titration is determined by what I perceived as; therefore I should use a colorimeter or other computerized measurement devices instead. Lastly‚ there was a large amount of hydroxy naphthol blue indicator (HNB) being used for complexometric titration. The HNB indicator affects the volume of solution and hence the concentration in the solution due to the large volume of indicator added. In order to rectify this‚ I could have used a more concentrated HNB indicator to possibly reduce

Laina Gray AP English 11/19/13 Doubles Tale of Two Cities describes contrasting situations dealing with London and Paris using a technique known as “doubling”. Dickens not only contrasts two ideas but also compares them to one another. This technique gives visual aid on whether something in the story is good or not so good. Contrasting London and Paris‚ the resemblance between Carton and Darnay‚ and the way that two opposite things can also be

Darry and Soda had different points of view on how to interact with their brother Ponyboy. On page 2‚ the books states‚ “Soda’s never hollering at me all the time the way Darry is‚ or treating me as if I am six instead of fourteen.” From this quote‚ the reader is told that Darry treats Ponyboy differently than Soda. It can be inferred that Darry is more strict with Ponyboy while Soda may not be as strict. On the other hand‚ “Soda’s always happy-go-lucky

Quantitative Analysis: % Copper in an Ore May 3‚ 2006 Abstract: In this experiment we were given an unknown sample of ore. Using the spectrophotometric analysis and the electrogravimetric analysis‚ we found the unknown percentage of copper in the unknown sample of ore was to be 17.6% by mass. Introduction: Chemical analysis takes place under two different scenarios. In one case‚ you need to find out the chemical identity of some material. The first kind of analysis‚ in which the chemical

The Determination of the Concentration of Hard Water Ions by the Titration of EDTA By Hannah Denby Lab partners: Heidi Kiziah‚ Leonie Hamel University of Central Florida‚ CHM 2046L December 3rd‚ 2015 Abstract. The “hardness” of water is a common dilemma attributed by high concentrations of metals such as calcium and magnesium. This is a result of the properties of water; because it is a good solvent‚ impurities are easily dissolved. As water moves through soil and rock‚ it dissolves minute amounts
