The inorganic speciation of tin(II) in aqueous solution

Effect of anions on the electrodeposition of tin from acidic gluconate baths

“…Specific distribution of the individual species depends mainly on the total concentration of ions, type and concentration of other compounds added to the bath, pH, and temperature. In aqueous solutions, tin(II) can appear as free Sn 2+ ions and soluble complexes with formulas dependent on the salt type and solution pH [19]. Precipitation of sparingly soluble tin(II) hydroxide is also observed.…”

The Influence of Tin(II) Incorporation on Visible Light Absorption and Photocatalytic Activity in Defect‐Pyrochlores

“…Unfortunately,t he exchange is poor,p robably duet op oor solubility and as ignificant amount of halide ions is detected after the ion exchange, even after several washing steps. [31] After ion exchange in water,S n 0.36 K 0.45 Ta 1 W 0.96 O 6 was obtained.T he direct band gap is 2.6 eV,w hich is ad iminishment of 1.0 eV ( Figure 6, left), while the indirect band gap is even smaller around 2.2 eV ( Figure S9, Supporting Information). Although Sn 2 + ions tend to hydrolyse, [30] stannous sulphate SnSO 4 shouldb es table at low pH values.…”

The XRD patterns confirm phase purity after the exchange, which is also affirmed by Raman-and DRIFT-spectra ( Figure S9, Supporting Information).…”

Effect of Sn on the Pitting Corrosion Behavior of Ultra‐Purified 17% Cr Ferritic Stainless Steel

“…Inhibition of the anodic reaction may not, therefore, be counteracted by activation of the cathodic reaction. Besides, three stable species of Sn 2+ , namely SnCl + , SnCl 2(aq) , and Sn may exist in the acidic mature pits (pH < 4.5), and the mixed hydrolytic Sn(OH)Cl (aq) species accounts for 60% of the Sn 2+ at pH ≈ 4.5 . These species may consume a large amount of Cl − and weaken hydrolysis process of Sn 4+ .…”
