What is the purpose of titration in a chemical reaction?

The purpose of titration in a chemical reaction is to determine the endpoint of a reaction. Titration is a quantitative analytical method used to establish the concentration of a solute in a solution. By slowly adding a titrant (a solution of known concentration) to a reaction mixture until the reaction reaches a specific endpoint, indicated by a color change or a measurable change in some property, chemists can accurately calculate the concentration of the unknown solution.

This method is essential in various chemical analyses, as it allows for precise control over the amount of reactant being added, facilitating the determination of how much of the reactant is needed to completely react with the sample. This information can then be used to derive important data about the reaction, such as stoichiometry and reaction rates.

In contrast, measuring temperature change, finding the mass of reactants, or analyzing gas emissions do not directly pertain to the core purpose of titration, which specifically focuses on determining the completion of a reaction through precise volumetric analysis.
