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.
Standardization is the process of determining the exact concentration (molarity) of a solution. Titration is one type of analytical procedure often used in standardization. In a titration, an exact volume of one substance is reacted with a known amount of another substance.The point at which the reaction is complete in a titration is referred to as the endpoint. A chemical substance known as an indicator is used to indicate (signal) the endpoint.The indicator used in this experiment is phenolphthalein. Phenolphthalein, an organic compound, is colorless in acidic solution and pink in basic solution. This experiment involves two separate acid-base standardization procedures.In the first standardization the molarity of a sodium hydroxide solution (NaOH) will be determined by titrating a sample of potassium acid phthalate (KHP; HKC8H4O4) with the NaOH. chemical substance known as an indicator is used to indicate (signal) the endpoint.
