• The slightly soluble white crystals which form when lead (II) nitrate is added to the lead (II) ethylenediaminetetraacetate complexes in acetate buffer solution have been investigated. From the chemical analysis, it was found that the crystals have the composition of lead (II) ethylenediaminetetraacetatoplumbate(II) monohydrate. The solubility product constant,<BR><I>K</I><SUB>sp</SUB>=[Pb<SUP>2+</SUP>][PbY<SUP>2−</SUP>]<BR>where Y<SUP>4</SUP> means an ethylenediaminetetraacetate anion was determined at ionic strength 0.2 as 3.54×10<SUP>−6</SUP>(mol./1.)<SUP>2</SUP> at 15°C, 4.34×10<SUP>−6</SUP>(mol./1.)<SUP>2</SUP> at 25°C and 5.72×10<SUP>−6</SUP> (mol./1.)<SUP>2</SUP> at 35°C.
