Reaction X Smp
+ Y Titr
Enter stoichiometric coefficients for the reaction between the sample
and the titrant when the following units have been selected:
•
Result unit molar or weight (mol, mmol, g, mg, µg, mol/l, mmol/l, g/
l, mg/l, mg/ml, µg/ml, mol/kg, mmol/kg, mg/g, mg/kg, %, g/kg, µg/g
or ppm),
or
•
Reagent unit molar (M, mM).
To determine the X and Y stoichiometric coefficients:
The reaction is: X Smp + Y Titr ->
where:
•
1 mole of titrant gives X eq of titrant
•
1 mole of sample gives Y eq of sample
To balance the reaction, Y mole(s) of titrant are required to titrate X
mole(s) of sample.
Example:
Titrant
sodium hydroxide (NaOH). 1 mole of NaOH gives 1 eq of NaOH.
Sample
citric acid (C
