Formation Constants for metal-EDTA Complexes

Reference: Quantitative Chemical Analysis, 9th Edition, Harris

The formation constants are for the reaction:

Mⁿ⁺ + Y^4- ⇌ MY^n-4

Values in the table apply at 25 ^oC and an ionic strength of 0.1 M unless indicated otherwise.

a. 20 ^oC, ionic strength = 0.1 M

b. 20 ^oC, ionic strength = 1 M
