The following calculation formulae are available for manual titration:
Titration formula
(ml1-B)*T*M*F1/(W*F2)
(B-ml)*T*M*F1/(W*F2)
(B*F3–ml*F1)*T*M/(W*F2)
(W*F2)/(ml-B)*M*F1)

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
"Weight", weighed-in quantity in g or volume in ml
