Notes:
A derivative of phenolphtalein, carrying two iminodiacetic acid groups, which enable the substance to bind metal cations, is described. Complex formation with Mg+2, Ca+2, Sr+2, Ba+2 and Zn+2 has been investigated quantitatively and the absorption spectra of the different complexes are given. The new substance, called Phtalein-Complexone, is an excellent indicator for the complexometric titration of alcaline earth metals. A method for the titration of sulfate is also given.
