1 Species Existing in Solution When a Metallic Ion Is Titrated with EDTA 

In a typical titration of a metal cation with EDTA tetraanion, the solution in the reaction vessel, among other species, contains the formed complex [MEDTA] +, free remaining metallic ions M +, hydroxo complexes resulting from their hydrolysis, and some complexes formed with a possibly present buffer. Usually, the latter are those formed with ammonia and with acids-alcohols (see Chap. 28).
