The Calcon (CI 15705) Analytical Grade by Dinâmica, available at LojaLab, is an azo dye used as a metallochromic indicator in complexometric titrations. Under appropriately alkaline conditions, it forms a colored calcium complex and allows visual detection of the EDTA endpoint as the metal is released from the indicator. The validated method must take precedence over generic color descriptions.
Characteristics
