Thermodynamic Data for Sn(IV) Species in Aqueous Solution: A Matter of Controversy and Error

Abstract Critically assessed data regarding Sn(IV) dioxides and hydroxy complexes have recently been challenged. Differences as large nine orders of magnitude occur in certain the published solubility products other equilibrium constants, despite supposedly being derived from same ‘reliable’ measurements. We show how these differing conclusions depend on assignments uncertainty respective experimental observations that divergence is due to error propagation identifiable thermodynamic analyses. The use Sn 4+ a ‘basis’/‘master’ species modelling deprecated. Automatic methods which enable necessary calculations be properly evaluated, well easily repeated, help uncover such mistakes. results comprehensive NEA review are substantially confirmed.
