What does the T stand for in Eriochrome Black T.
Yes, It's actually the same. :) Solochrome Black T is actually the "other" name of Eriochrome Black T.
titration
eriochrome black T is an indicator for EDTA titration
If for you EBT is eriochrome black T, this compound form a complex with magnesium ions.
Eriochrome Black T (protonated form) produce a complex with some metal ions.
çünkü öyle gerekti yeğen araştırıyorum bulursam yazarım neden =)
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 blact T
The indicator added to the sample is Eriochrome Black T. Initially, the indicator will form a complex with the cations. When complexed it is red in color. As the EDTA is added dropwise to the sample, it replaces the Erio T and forms more stable complexes with calcium and magnesium. When the indicator is released by the metal ions, it has a distinct blue color. Therefore, the endpoint of the titration is marked by the color change form red to blue
phosphoric acid can be tested by titrating a a given sample of soft drinks with diethyle ether in the presence of eriochrome black t as a indicator...
