Discussion/Conclusion Various aspects of the nature of chemical reactions and how they work were explored in detail in this experiment. The nature of aqueous solutions was studied by making solutions from measured amounts of salts and stock solutions and by diluting acids. Once the solutions had been made, their conductivity was measured in micro-Siemens per centimeter and recorded. The conductivity was measured by each group as opposed to sharing data to prevent mistakes made during one measuring from offsetting the results of everyone. As the data was gathered it was seen that the relationship between conductivity and number of ions was linear. The data is in accordance with the concepts studied thus far because conductivity depends on the number of ions in the solution, thus an increase of one leads to the increase of the other. The same observations were true for the acids. The lowest conductivity was had by the acetic acid, the

Unformatted text preview: weakest of the three acids, followed by phosphoric acid and hydrochloric acid being the strongest. In order to fully explore the nature of chemical reactions, it is important to also explore the different types of chemical reactions. The different types of reactions were observed in several opportunities during the experiment and observations were taken on them to later determine what type of reaction they were. If a precipitate formed then it was determined that the reaction was a precipitate reaction. Because of the application of the universal indicator, color change was the main observation associated with the acid-base reactions. The more dramatic observations of the reactions, such as bright lights and rise in temperature were associated with the redox reactions. The experiment was used to show the properties of chemical reactions by careful observation of the reactions before, during and after it occurred....
