Volumetric Analysis Volumetric analysis is based on the principle of stoichiometry where the relationship between reactants is quantified By precisely measuring the volume of a solution of known concentration the titrant required to react completely with a solution of unknown concentration the analyte we can calculate the concentration of the analyte Key Concepts and Procedures Titration The core process involves adding the titrant to the analyte dropwise until the reaction reaches the equivalence point often signaled by a color change from an indicator Equivalence Point The point where the moles of titrant equals the moles of analyte crucial for accurate calculations This is often difficult to measure directly and needs the careful use of indicators Indicator A substance that changes color at or near the equivalence point providing a visual signal for the completion of the reaction Different indicators are appropriate for different reactions Standardization Before conducting a titration the titrants concentration must be precisely known This step often called standardization involves titrating a primary standard solution to establish the titrants accuracy
