5.2.5 Back Titration
The equation used in back titration calculations is also similar to the equation for a blank
titration. Instead of subtracting the initial amount of titrant needed to react with the blank,
the amount of second titrant needed to react with the excess titrant added in the first titration
is subtracted from the amount of the first titrant added. The difference between the two
amounts is the amount of titrant necessary to reach the first equivalence point.
