What is example of indicator in EDTA titration?
eriochrome blact T
Why are indicators in complexometric titration added in a solid form?
Indicator is added to zinc because firstly it combines with zinc and forms zinc-indicator complex and after addition of more EDTA to the complex , the zinc which was in the form of complex gave free indicator and forms Zn-EDTA complex and the free indicator gaves blue colour which indicates end point of titration.
Why is the pH of the medium important in edta titration?
why is the pH of the meadium important in EDTA titration
What are different types of EDTA titration?
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.

Determination of magnesium in tap water?
u can use titration with EDTA or use flame atomic absorption.. but titration with EDTA is the easiest
What is the purpose of standardizing EDTA in Complexometric titration?
we standardize edta to make the soln stable complex
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 do we heat KSCN Fe solution befor titration with EDTA?
We usually heat KSCN Fe solution before titration with EDTA so as to produce crystalline crust forms.
Why do buffers added in EDTA titration?
to maintain constant ph
Why titration with standard hard water is carried out?
To determine concentration of EDTA.
