surface chemistry versus solution chemistry

Heterogenous nature - Colloidal sols are biphasic in nature. It consists of the dispersed phase and the dispersion medium. In the colloidal solution, each particle is contained within its own surface boundary and therefore has a separate existence from the dispersion m..

Solubility of a salt in water depends on Lattice energy versus hydration energy Lattice energy (amount of energy required to break one mole of a solid salt into its ions). Greater the lattice energy, more will be the energy required to break the lattice. Hydration energy (amount ..

C 6 0 molecule is a symmetrical structure of fused-ring of aromatic system containing 20 hexagons and 12 pentagons of sp 2 hybridized C atoms. The structure bends around and closes to form a soccer ball shaped molecule. It is therefore, called buckyball or C 6 0 fullerene. The diameter of bal..

Introduction - Surface chemistry is the study of processes that occur at the interface of two bulk phases. The bulk phases can be of the type solid-gas, solid-liquid, liquid-gas and liquid-liquid. There is no interface between gases because of their complete miscibility. The bul..

Definitions of solute and solvent The dissolving process as a result of random molecular motion Temperature, pressure, and surface area - their affect the dissolving process Concentration of a solute in terms of grams per liter, molarity, parts per million and ..

Conclusion - Adsorption is a surface phenomenon. In this process there is accumulation of a substance on the surface of a solid or a liquid as compared to the bulk of the solid or liquid. The substance which is adsorbed is called the adsorbate and the substance on to whose ..

Adsorption of solutes from solutions also takes place on solids. Process of adsorption is used to reduce colors from solution. For e.g., raw sugar solution is decolorised by charcoal. Chromatographic separation of a mixture of compounds in solution ..

In this type of deviation, the partial vapor pressure of each component of solution is less than the vapor pressure as expected according to Raoult's la..

Gases can be dissolved in suitable liquids. The solubility of a gas in any liquid depends upon: * Nature of the gas and the liquid. * Temperature of the liquid. * Pressure of the gas over the surface of the solution..
