Composition and stability constants of Mn(II) complexes with acetic, glycolic (hydroxyacetic), methoxyacetic and phenylacetic acids, glycine (aminoacetic acid), and sarcosine (N-methylglycine) were determined, at a constant ionic strength = 0.1 KNO3 using the potentiometric method at 20 graduate C. Values of stability constants were found by Bjerrum graphical method and also numerically using Martell and Motekaitis program. The following logK1,graph. values of Mn(II) complexes were found: 2.21 for the complex with acetic acid, 2.45with glycolic acid, 2.10 with methoxyacetic acid, 2.48 with phenylacetic acid, 3.10 with glycine and 3.05 with sarcosine.
