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
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.
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.
