Post by: Asim on June 18, 2021, 04:05:49 PM
Eosin-Y indicator is Untied State pharmacopea mentioned indicator.
But in titration , final colour of indicator disappears on standing the solution for 2 minutes.. also it does not give sharp colour change . Thats why no satisfacory results are obtained..
Can any one help how to get accurate results using Eosin-Y indicator ??

You haven't described what you did, so it's hard to give advice.

Eosin-Y indicator does not shows sharp color change, is there any other indicator used in replacement of Eosin-Y ??
