Complexometric titration reaction
WebIndicators for EDTA titrations The accuracy of the indicator’s end point depends on the strength of the metal-indicator cpx relative to that of the metal-EDTA cpx. If the M-In cpx is too strong, the change in colour occurs after the equiv. point however if the M-EDTA cpx is too weak, the end point occurs before equiv. point. Most metallochromic indicators also … Web9.3: Complexation Titrations. The earliest examples of metal–ligand complexation titrations are Liebig’s determinations, in the 1850s, of cyanide and chloride using, respectively, Ag + and Hg 2+ as the titrant.
