Key aspects of EDTA titrations:
Common metallochromic indicators:
For accurate results:
Common applications include:
[M] = (VEDTA × MEDTA) / Vsample
Where:
V = Volume
M = Molarity
K'f = Kf / α
Where:
Kf = Formation constant
α = Side reaction coefficient
log α = log(1 + K[L])
Where:
K = Formation constant
[L] = Ligand concentration
