what is the purpose of indicators in titration
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.
Titration is a laboratory method used to determine the unknown concentration of a reactant. This is a delicate procedure that requires patience and a good observation skills.Usually, an indicator is used in titration to determine the endpoint of the reaction.Once the endpoint volume is found, mathematics can be used to determine the concentration of the unknown. This procedure is commonly used in the field of analytical chemistry.sually, an indicator is used in titration to determine the endpoint of the reaction.
