Eriochrome Black T is a complexometric indicator that is used in complexometric titrations , e. It is an azo dye. In its deprotonated form, Eriochrome Black T is blue. It turns red when it forms a complex with calcium , magnesium , or other metal ions. When used as an indicator in an EDTA titration, the characteristic blue end-point is reached when sufficient EDTA is added and the metal ions bound to the indicator are chelated by EDTA, leaving the free indicator molecule. Eriochrome Black T has also been used to detect the presence of rare earth metals. Contents move to sidebar hide. Article Talk. Read Edit View history. Tools Tools.

Eriochrome Black T is a complexometric indicator. During titrations of water hardness determination process. Stability: :Stable. Incompatible with strong oxidizing agents, strong reducing agents. 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.

Objectives: To study the basics of complexometry and know the following about self generated questions. These titrations involve combination of ions with organic ligand to form dissolved complex with analyte a metal ion. Usually metals accept 2, 4 or 6e — pairs coordination number. Figure 1: 1,2-Ethylenediamine as a chelating ligand for metal ion. Chelate effect: chelate effect is observed with polydentate ligands as they form thermodynamically more stable complexes.

Eriochrome Black T is a complexometric indicator that is used in complexometric titrations, e. It is an azo dye. EBT binds with free metal ions in the water to form a pink complex. The blue color is used as the end point in the titration. It functions as an acid-base indicator. Answer and Explanation: Eriochrome black T is used as an indicator for complexometric titrations because it forms a colored complex in its protonated form with calcium, magnesium, and other metal ions. Local offices are also listed in the State or local government pages of the telephone book.
