In this study, solubility measurements on di-calcium ethylenediaminetetraacetic acid [Ca₂C₁₀H₁₂N₂O₈(s), abbreviated as Ca₂EDTA(s)] as a function of ionic strength are conducted in NaCl solutions up to I = 5.0 mol•kg^–1 and in MgCl₂ solutions up to I = 7.5 mol•kg^–1, at room temperature (22.5 ± 0.5oC).
