5.2.3. STANDARDIZE TITRANT BY MASS
Titrant standardization is the second most important calculation in titrations. A primary standard is titrated in order
to determine the concentration of the titrant. This is essentially a typical titration calculated in "reverse", where the
concentration of the solution is known and the titrant is unknown.

5.2.5. BLANK TITRATION
In a blank titration a pre-titration is performed, often times on the solvent to be used for the sample titration, and the
titrant volume required to reach the endpoint is noted. This blank value nullifies error due to titrant required to react with
the components of the titration solution matrix. The basic titration equation can be used for a blank titration, with the
single modification that the volume of titrant used in the blank titration should be subtracted from the regular titration
titrant volume.
