Investigation of the hydrolysis of [Sn(CH3)3(H2O)2]+ in aqueous solution by tin-119 nuclear magnetic resonance spectroscopy
Abstract
The hydrolysis of [Sn(CH3)3(H2O)2]+ has been investigated using 119Sn NMR spectroscopy in aqueous solution at 25°C and ionic strength 0.5 mol dm–3. The ionic strength was adjusted using KCl, KNO3 or NaClO4. The chemical-shift data were processed using the computer program EQNMR to yield the stability constants and the chemical shifts of the various species present in solution. The results are compared with literature data obtained using other techniques.
