Speciation Studies of Dimethyltin (IV) and Trimethyltin (IV) - Carboxylates Systems
Journal Title: International Journal of Science and Research (IJSR) - Year 2015, Vol 4, Issue 2
Abstract
Speciation studies of the systems involving interaction of dimethyltin(IV) [DMT]and trimethyltin (IV)[TMT] cations with adipic acid, citric acid, tartaric acid and phthalic acid have been determined in aqueous solution in the pH range 2.7 to 10.5 at three different temperatures (20±1°C, 30±1°C and 40±1°C) and at three ionic strengths (µ=0.05 ,0.10 and 0.15 M), using potentiometric technique. The computational analysis is done using standard mathematical approaches and SCOGS (stability constant of generalized species)computer programme. The formation of protonated , nonprotonated and hydroxo species in various systems is presented in the form of distribution curves.The thermodynamic stabilities of DMT species are found to be more than TMT(IV) species. Based on coordination the stability trend for various ligands is found to be :Phthalic acid > Tartaric acid >Adipic acid > Citric acid.
