What is another example of indicator that used in titration with EDTA?
eriochome black T
Why you use eriochrome black T indicator in EDTA titration?
çünkü öyle gerekti yeğen araştırıyorum bulursam yazarım neden =)
What is the function of starch solution in the redox titration?
It is used as indicator for the endpoint of a Iodometric (redox) titration: it gives a bluish grey to black color with very minute excess of Iodine-iodide ions (I3-)
What is the structure of ebt indicator?
EBT is also known as Erichrome Black T and is useful in titrations with EDTA where it starts as a dark/wine red colour and changes to a deep blue in titrimetric analysis.
What is the nature of eriochrome black-t?
Eriochrome Black T is a complexometric indicator that is part of the complexometric titrations, eg. in the water hardness determination process. It is an azo dye. In its protonated form, Eriochrome Black T is blue. It turns red when it forms a complex with calcium, magnesium, or other metal ions. Its chemical formula can be written as HOC10H6N=NC10H4(OH)(NO2)SO3Na.

It is the same mordant black and eriocrome black?
No you need to not

How do you draw the structural formula for EBT?
Probably you meant: (the only chemical meaning of EBTamong more than 15 ambiguous homonyms)Eriochrome Black TThis is a blue complexometric indicator that turns to red upon the formation of a metal-complex in complexometric titrations. Structural formula: can be found as 'Related link' just right down this answer page.Formula: C20H12N3O7SNa (or HOC10H6N=NC10H4(OH)(NO2)SO3Na)IUPAC name:sodium (4Z)-4-[(1-hydroxynaphthalen-2-yl-hydrazinylidene]-7-nitro-3-oxo-Y-naphthalene-1-sulfonate
How is an indicator used to determine the pH of a solution?
Iodine solution is an efficient indicator for starch. It will go from a light brown colour to a black colour if starch is present and will stay light brown if no starch is present. Hope this Helps!
Why is starch solution used as indicator in Sodium thiosulphate Iodine titrations instead of phenolphthalein indicator?
Phenolphthalein is an acid base indicator - it does not show the end-point in a thiosulfate type titration. Starch gives a very sharp end-point from a blue-black to colorless end-point when titrating iodine with thiosulfate. Phenolphthalein would just not detect this change.
What is the meaning of T in Eriochrome Black - T?
