NOT KNOWN FACTUAL STATEMENTS ABOUT METAL INDICATORS

To stay away from this problem of gradual change in colour, a small degree of 1:1 EDTA:Mg is frequently included on the titration flask (this doesn't have an effect on the stoichiometry of thetitration response as the quantities of EDTA and Mg are equimolar) becauseMgIn complex is adequately steady that it's going to not dissociate appreciably prio
