DIRECT TITRATION DOSAGE
Definition
Schematic
Before the equivalence, the limiting reactant is the titrating reactant. After the equivalence, it is the titrated reactant.
The EQ= the moment of titration where there is a change of reactant.
At EQ, the quantities of matter of the titrating and titrated reactants are introduced in stoichiometric proportions.
nia/a = nib/b Ca x Va/a = Cb x Vb,eq/b
>Ca=a x Cb x Vb,eq/ Va x b
At the final state: Xf= C1 x V1/ a= x and C2 xV2,eq/b =x
To Remember:
n= CxV
C=n/V
At EQ: ns2O3 2-= 2xNI2
A dosage by titration is destructive
