✦ Synopsis

Th:s mvcstigatlon has lxcn supported by grants from Statens Xaturvctcnskapltga Kommlssion, fimlancl. The authors wish to thank Geigy Co 1,td., Switzcrlancl, for placing samples of EGTA at their disposal. SUJlXlr\RY In the prcsencc of magnesium, calcium can bc titrated complcxomctr~cally with EGTA (cthylcncglycol-bls-aminocthylcthcrtctraacctic acid = GClgy Chcl DE = H&) using Zincon + ZnS as inclircct indicator. 'I'hc stability constants of the zinc complcxcs of EGT:\ and Zmcon have been dctcrmincd, and sultablc experimental conditions have been sugjicstccl on the basis of thcorctical considerations. The results of some titrations arc presented.
