1. Direct Titration
In direct titration, you simply add an indicator to the solution of the metal ion and titrate with EDTA. Before starting the titration,it is needed to check that the pH of the solution to obtain a good formation constant value and on the other hand indicator colour change as well.
2.Indiract titration
EDTA can be used as titrant for anions. Anions can be precipitated with suitable metal ion. Filter and wash the ppt with proper solution. Then boil in excess EDTA to complex metal ion(ppt). Back titrate to determine how much metal ion you had.
3.Back Titration
In a back titration an excess of EDTA is added to the metal ion solution, and the excess EDTA is titrated with a known concentration of a second metal ion. The second metal ion must form a weaker complex with EDTA than the analyte ion so the second metal does not displace the analyte ion from its complex with EDTA.
4.Displacement titration
Here the analyte is treated with an excess of a second metal bound to EDTA. The analyte ion displaces the second metal from the EDTA complex, and then the second metal is titrated with EDTA.

Why edta titration is known as complexo metric titration?
EDTA reacts to form so called 'one to one'-complexes with all bi- and tri-valent metal ions

Why titration with standard hard water is carried out?
To determine concentration of EDTA.
Difference between precipitation titration and complexometric titration?
During a precipitation titration an insoluble precipitate is formed.Complexometric titration is a type of volumetry which use as titrants EDTA or other similar reagents.
What is another example of indicator that used in titration with EDTA?
eriochome black T
Determination of fe3 with EDTA by photometric titration?
Iron (III) ions form a deep-coloured complex with a maximum absorption at about 525nm; this complex is used as the basis for the photometric titration of iron(III) ion with standard EDTA solution.
