difference between surface chemistry and solution chemistry

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..

Adsorption from Solutions - 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 mixtu..

In the process of absorption molecules of one phase interpenetrate uniformly among those of another phase to form a solution with the second phase. In adsorption, molecules of one phase are present in higher concentration at the surface of the second phase. Water vapor is ..

Coagulation is the process by which a colloid precipitates out of a solution. The precipitation is brought about by induced aggregation. For e.g., an iron (III) hydroxide sol can be made to aggregate by addition of an ionic solution. A positively charged particle of ir..

Colloids have uses in our daily life as well as in various industrial processes. Some of the applications where colloids are present are listed below. 1) Pharmaceutical industry makes use of colloidal solution preparation in many medicines. A wide variety of medicines are emulsions. An ex..

Crystals are solid particles bounded by plane surfaces, which make definite angles with each other. This gives a definite geometrical shape to the crystal. These shapes are different for different crystals (Fig.6.13). Crystals of the same substance are identical only ..

This technique is based on the differential adsorption of various components of a mixture on a suitable adsorbent called the stationary phase while the liquid in which the substance is dissolved is called the mobile or moving phase. Depending on the nature of the two phases there are various types..

Origin of Electrode Potential - Consider a zinc rod being dipped in ZnSO 4 solution. The zinc atoms on the surface of the metal with in the solution have tendency to release Zn + 2 into solution retaining the electrons on the surface of the metal. T..

>Sedimentation followed by Decantation is used to separate an insoluble solid from a liquid. Filtration is a more effective method of separating an insoluble solid from a liquid. A soluble solid can be reobtained from a liquid in which it dissolves by the process of evaporation. Distillation is emp..
