acctually im not that familier..
it's used essentially in EDTA titration, when the components of the hard water is comlexed with the EDTA making a red comlex..the blue colour of the uncombined EBT marks the end-point
hope it helps!

good luck

AFAIR EBT is a pH indicator by itself, google for its color changes dependent on pH.
