The particular pH used to buffer the titration solution was also chosen because of the metal ion indicator used to signal the end point in the titration. A metal ion indicator is a substance that changes color when it binds to metal ions in solution.
Applications: analytical chemistry, indicator (metals), in biochemistry. the indicator eriochrome black T (EBT) is used to signal the presence of ions in the water sample. EBT binds with free metal ions in the water to form a pink complex.
