Solution equilibria and characterization of the complex formed between hippuric acid and tin(II)
Apstrakt
The complex formation equilibria in tin(II) - hippuric acid (Hhip) solutions were investigated by potentiometric glass electrode measurements in 1.0 mol/L NaCl ionic medium at 298 K. Non-linear least-squares analysts of the obtained results indicate that in the concentration range of tin(II) between 0.5 and 2.5 mmol/L and concentration ratios [hip](tot)/[Sn-0(2+)](tot) between 1:1 and 10:1 and 1.5 LT - log h LT 3.0 the complexes Sn(hip)(+) and Sn(OH)hip are formed with the overall stability constants 4.53 +/- 0.03 and 1.20 +/- 0.10 respectively. The hydrolytic precipitate, Sn(OH)hip, formed in the pH interval 5.0-6.0, was isolated from the solution and characterized by elemental analysis, scanning electron microscopy, thermogravimetry, X-ray powder diffraction and i.r. spectroscopy.
