Hydrolytic Behavior of Metal Ions. VIII. Ultracentrifugation of Bismuth(III) in Perchlorate Solution^1,2

Electrocatalysis of Anodic Oxygen‐Transfer Reactions: Application of an Electrochemical Quartz Crystal Microbalance to a Study of Pure and Bismuth‐Doped Beta‐Lead Dioxide Film Electrodes

“…They speculated that the C1 might have originated from C1-impurity in the HC104 (12). Some evidence has been reported (13,14) that Bi(III) might exist in HC104 solutions as the ion pair Bi(OH)2C104 (13,14), and we suspect that C10( and not C1 was the source of the C1 found by Nielson et al (12). Nielson et al found some C1 in PbQ films deposited from HC10~ solutions, but only in the outer layers.…”

Intercalation of polyoxycation species into conducting layered host lattices of molybdenum trioxide and tantalum disulfide

“…A solution of the Al13 polyoxycation (0.1 mol/dm3 in Al) was prepared by dissolving powdered aluminum chlorohydrate (ACH) (Reheis Chemical; 47% of A1203) in water and aging at 80 °C for 2 h. 3 The Bi polyoxycation was made by dissolving Bi2G3 in an equivalent amount of concentrated HC104. 18 Intercalation of the polyoxycations was carried out via ion exchange of sodium ions in freshly prepared Na0 2s(H2O)>.MoO3 and Na0 33(H2O)>,TaS2. The solids were treated with an excess © of aqueous solutions of the metal polyoxycations for 48 h at room temperature.…”

Measurements and Modeling To Determine the Reduction Potential of Uncomplexed Bi(III) in Nitrate Solutions for Application in Bi(III)-Ligand Equilibria Studies by Voltammetry

“…[9][10][11] There was also indication of the formation of bismuth polynuclear species with much debate as to the exact stoichiometry of these species. [12][13][14] Evidence from various techniques supported the presence of the hexamer, Bi 6 (OH) 12 6+ , as the dominant species under the specific experimental conditions. 10,11,[14][15][16][17] This species could also be referred to as Bi 6 O 6 6+ because numerous techniques have difficulty in differentiating whether O 2 or OH  is bound to the metal ion.…”

“…Bi­(III) hydrolysis, however, has been extensively studied and was instrumental in developing techniques to investigate hydrolysis of metal ions in general . The formation of the Bi­(OH) 2+ species was confirmed early on. − There was also indication of the formation of bismuth polynuclear species with much debate as to the exact stoichiometry of these species. − Evidence from various techniques supported the presence of the hexamer, Bi 6 (OH) 12 6+ , as the dominant species under the specific experimental conditions. ,,− This species could also be referred to as Bi 6 O 6 6+ because numerous techniques have difficulty in differentiating whether O 2 – or OH – is bound to the metal ion . It was also recognized that the hexameric species was in equilibrium with even larger complexes proposed to be Bi 9 (OH) 20 7+ , Bi 9 (OH) 21 6+ , and Bi 9 (OH) 22 5+ . ,, …”
