Fig. 57
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)
ml
Legend of the abbreviations used:
ml:
Titration solution consumption in ml
B:
Blank value in ml, in most cases determined by titration
T:
Titer of the titration solution (e.g. 0.09986)
M:
Mol; Mol- or equivalent weight of the sample (e.g. NaCl 58.44)
F1
Factor 1, Conversion factor
F2
Factor 2, Conversion factor
W
Weight, sample weight in grams or sample volume in ml.
