In a titration, the primary goal is to determine the concentration of an unknown acid or base solution. This process typically involves adding a titrant, which has a known concentration, to the analyte until the reaction reaches its equivalence point. At the equivalence point, the number of moles of acid equals the number of moles of base, allowing for the calculation of the concentration of the unknown solution based on the volume of titrant used.

While color change can be an indicator of reaching the endpoint of the titration, it does not provide quantitative information directly about the concentration of the reactants involved. The exact mass may be relevant in certain calculations to find concentrations, but titrations typically rely on volume measurements rather than mass. Measuring the pH level can provide information about the acidity or basicity of a solution but does not quantify the concentration of the acid or base unless conducted with additional calculations and methods. Thus, in the context of a titration, identifying the concentration of the unknown substance is the critical outcome.
