The integration of global markets by the reduction trade barriers, improved communication, foreign direct investment, and other means. Globalization allows a multinational corporation to make a product in one country and sell it in another.
2. An indicator is used to determine the equivalence point of a solution. Most indicators are weak acids that shift from acid to conjugate base forms. The color will change as the pH of the solution changes as a result.urpose. The purpose of this lab is to perform a titration, using 10.0 mL of 1.5 M HCl to determine the molarity of a solution of NaOH with an unknown concentration with the use of the indicator phenolphthalein.
Complexometric titration (sometimes chelatometry) is a form of volumetric analysis in which the formation of a colored complex is used to indicate the end point of a titration. Complexometric titrations are particularly useful for the determination of a mixture of different metal ions in solution.An indicator capable of producing an unambiguous color change is usually used to detect the end-point of the titration.DTA forms an octahedral complex with most 2+ metal cations, M 2+ , in aqueous solution. The main reason that EDTA is used so extensively in the standardization of metal cation solutions is that the formation constant for most metal cation-EDTA complexes is very high, meaning that the equilibrium for the reaction:
