Abstract:
The electrochemical behaviour and deposition of indium in electrolytes composed of 0.4 mol dm-3 In(Tf2N)3 and 0.4 mol dm-3 InCl3 in the solvents 1,2-dimethoxyethane and poly(ethylene glycol) (average molecular mass of 0.400 kg mol-1, PEG400) was investigated. Indium(i) was identified as the intermediate species that disproportionated to indium(iii) and indium(0) nanoparticles. The presence of nanoparticles was verified by TEM analysis. SEM analysis showed that deposits obtained at room temperature from 1,2-dimethoxyethane were rough, while spherical structures were formed in PEG400 at 160 °C.

Electrolytes: van't Hoff Factor
The colligative properties of a solution depend only on the number, not on the identity, of solute species dissolved. The concentration terms in the equations for various colligative properties (freezing point depression, boiling point elevation, osmotic pressure) pertain to all solute species present in the solution. Nonelectrolytes dissolve physically without dissociation or any other accompanying process. Each molecule that dissolves yields one...

Aqueous Solutions and Heats of Hydration
When ionic compounds dissolve in water, the ions in the solid separate and disperse uniformly throughout the solution because water molecules surround and solvate the ions, reducing the strong electrostatic forces between them. This process...
