The following calculation formulae are available for manual titration:
Titration formula
Additional information
(ml1-B)*T*M*F1/(W*F2)
Formula for calculating the concentration of a
sample taking into account a blank value in
terms of ml.
(B-ml)*T*M*F1/(W*F2)
Formula for calculating the concentration of a
sample taking into account a blank value in
terms of ml. Reverse titration (examples. CSB,
saponification number)
(B*F3–ml*F1)*T*M/(W*F2)
Formula for calculating the concentration of a
sample taking into account a blank value,
including a multiplicative factor. Reverse
titration.
(W*F2)/(ml-B)*M*F1)
Formula for calculating a titer (T) of a titration
solution.
EP1
Used to calculate the consumption in ml
The abbreviations used here have the following meaning:
ml: Titration solution consumption in ml
B: Blank value in ml. Mostly determined by way of titration
T: Titer of the titration solution (e.g. 0.09986)
M: Mol; mol- or equivalence weight of the sample (e.g. NaCl 58.44)
F1 Factor 1, Conversion factor
F2 Factor 2, Conversion factor
W “Weight“, weighed-in quantity in g or volume in ml
