If the method uses the blank option, the following equations are taken into account and use the
same rules for the determination of the coefficient as above. The blank titration gives a B
volume of titrant delivered for an addition of excess titrant considered to be the same as the
one delivered for the sample analysis.
If you ask the result in volume, the result is calculated as follows:
Otherwise, this volume B is modified to give:
Then the result is calculated with the following equation:
