Standardization is the process of determining the exact concentration (molarity) of a solution. Titration is one type of analytical procedure often used in standardization. In a titration, an exact volume of one substance is reacted with a known amount of another substance.

Chapter 8: Sampling, Standardization, and Calibration. A chemical analysis uses only a small fraction of the available sample, the process of sampling is a very important operation. Knowing how much sample to collect and how to further subdivide the collected sample to obtain a laboratory sample is vital in the analytical process.
Standardization is the process of determining the relationship between the signal and the amount of analyte in a sample. Previously, we defined this relationship as Stotal=kACA+Sreag where …
