Eriochrome Black T is a complexometric indicator commonly employed in tests for water hardness, particularly during EDTA titrations. It transitions from wine-red to blue as it binds and subsequently releases metal ions such as calcium and magnesium, facilitating the determination of their concentration in a solution.
