indicate the end point of a titration) titrations as it forms stable complexes with most metal ions. EDTA is a tetracorboxylic acid and in alkaline conditions‚ it exists as Y⁴⁻ ions‚ which form 1:1 complexes with metal ions like nickel(II) ions: Y⁴⁻ + Ni²⁺ NiY²⁻ A metal ion indicator (an organic dye which changes colour when it binds with metal ions) shows the end of an EDTA complexometric titration. However‚ for a metal ion indicator to be suitable in n EDTA titration‚ it must not bind as strongly

Absorption Spectra of Conjugated Dyes 04-21-2103 Introduction: The visible absorption bands or conjugated dye arise from electron transitions involving the electrons in the conjugated and they are free to move along the chain and are not attached to any atom. An example of such a dye is 3‚3-diethyl-thiacyanine iodide. The cation has two resonance forms causing each of the bonds in the conjugated chain to have an order of 1.5 and have a length similar to the C--‐C bond length in benzene
