Photostimulated oxidation of Sn(II) in aqueous solutions: Spectral sensitivity and quantum yield

The spectral sensitivity of Sn(II) complexes in acid and alkaline solutions of SnCl2 in photostimulated oxidation with oxygen was studied. The reaction mechanism was revealed. A spectrophotometric method for prompt monitoring of the composition of SnCl2 solutions was proposed.

Reactions of octacyanomolybdate(V) and octacyanotungstate(V) with s 2 metal-ion reducing centers

The s2 centers, Sn(II), Ge(II), and In(I) reduce Mo v(CN)83- and Wv(CN)8 3- quantitatively to the corresponding octacyanomolybdate(IV) and -tungstate(IV) anions. Reductions by In(I) proceed 103-10 5 times as rapidly as those by Sn(II) and Ge(II). All reactions are triggered by a single electron oxidation, yielding a much more reactive s I intermediate. Reductions by Sn(II) in chloride medium proceed predominantly through the SnCl3- anion. The Ge(II)-W(CN) 83- reaction is initiated by a slow unimolecular heterolysis of the Ge(II) center, yielding very nearly linear profiles when the reductant is in excess.

Oxidation of Tin(II) in Sulfuric Acid Solutions: Effect of Copper Ions

Copper ions increase the rate of oxidation of tin(II) with atmospheric oxygen in continuously stirred sulfuric acid solutions of compositions corresponding to bronzing electrolytes. For tin(II), this reaction is of the zero order. The reaction order in copper ions decreases with an increase in the concentration of copper ions, approaching zero. The reaction rate decreases with an increase in the concentration of sulfate ions and a decrease in acidity. The dependence of the reaction rate on the concentration of copper and sulfate ions is explained by the possible formation of catalytically inactive binuclear copper(II) sulfate complexes. The inhibiting effect of hydroquinone, quinone, and cobalt(III) ions, characteristic of chain reactions, is established. The effect of each of these inhibitors on the reaction kinetics is shown.
