Concept introduction:
Volumetric principle:
The volume and concentration of unknown solution is determined by it is titrate with known volume and concentration solution.
The volume and concentration of unknown solution is required equivalent volume and concentration of known solution in the volumetric titration.
Where,
Degree of dissociation:
The ratio of mole of reactant that underwent to dissociating to mole of initial reactant is known as degree of dissociation.
In EDTA the degree of dissociation is,
If pH is fixed, the degree of dissociation
Where,
