Eriochrome Black T is a complexometric indicator. During titrations of water hardness determination process. Eriochrome Black T is BLUE in colour but in the presence of calcium, magnesium, or other metal ions It turns RED.

Eriochrome Black T or EBT plays colour changing role in between 6.3 to 11.5, and with RED as its acidic colour and ORANGE its basic color. 

Stability: :Stable. Incompatible with strong oxidizing agents, strong reducing agents.

Eriochrome Black T, Reagent, ACS is complexometric indicator also known as Solochrome Black T.  Most popular to used as an indicator in EDTA titration. Also used in many high-purity applications and typically designate the highest quality chemical available for laboratory use. 
Spectrum Chemical manufactured Reagent ACS grade products meet the toughest regulatory standards for quality and purity.
