Standardization vs. Titration: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Updated on October 19, 2023
Standardization is determining the concentration of a solution using a known substance, while titration is the process of adding a solution of known concentration to another solution to determine its concentration.
Key Differences
Standardization is a laboratory procedure wherein the exact concentration of a solution is determined. This process is commonly carried out using a primary standard, a substance of known purity. On the other hand, titration involves gradually adding a solution of known concentration (titrant) to another solution until the reaction between them is complete, often indicated by a color change.
Standardization typically uses a primary standard, which is a highly pure substance. Its concentration is then used as a reference in future experiments. Titration, in contrast, can be used to ascertain the concentration of an unknown solution, using the known concentration of the titrant.
Standardization often precedes titration in many experiments. This is because before a titration can accurately measure the concentration of an unknown solution, the concentration of the titrating solution itself must be known, which is ascertained through standardization.
In the standardization process, the reaction’s end point is usually marked by a clear physical change, such as a color shift. Similarly, in a titration, an indicator or a pH meter is used to signal the end point or equivalence point, where stoichiometrically equivalent amounts of the reactants are combined.
Both standardization and titration are integral procedures in analytical chemistry. Standardization ensures the accuracy of concentrations for reagents used in the lab. Titration, utilizing the known concentrations, can then be employed to determine unknown concentrations in samples.
