Solubility particle attraction

In this paragraph only two physical properties are discussed viz. the boiling point and solubility. These properties are affected by the attractive forces which the particles of the pure substance or in a mixture exert on each other. Particles attract when they are charged, so when they are ions, when they possess a dipole or when they are able to form hydrogen bridges. 

The attraction between the air bubble and contaminants is believed to be primarily a result of particle surface charges and bubble size distribution. The more uniform the distribution of water and microbubbles, the shallower the flotation chamber can be. Generally, the depth of effective flotation chambers is between 0.9 and 2.7 m (3 and 9 ft). Flotation units can be round, square, or rectangular. Gases other than air can be used. The petroleum industry has used nitrogen, with closed vessels, to reduce the possibilities of fire. Ozone can be fed through with air for more efficient reduction of soluble iron, VOCs, and so on.57 Ozone-UV flotation is another alternative for groundwater decontamination. 

Organic compounds that have the same functional group often have similar physical properties, such as boiling points, melting points, and solubilities. Physical properties are largely determined by intermolecular forces, the forces of attraction and repulsion between particles. Three types of intermolecular forces are introduced below. You will examine these forces further in Chapter 4. 

I he solubility of a solute is its ability to dissolve in a solvent. As you might X expect, this ability depends in great part on the submicroscopic attractions between solute particles and solvent particles. If a solute has any appreciable solubility in a solvent, then that solute is said to be soluble in that solvent. 

Solubility also depends on attractions of solute particles for one another and attractions of solvent particles for one another. As shown in Figure 7-16, for... 

In gas-liquid partition chromatography (GLPC), the stationary phase is a liquid that coats the particles in the tube or the walls of the tube. Often the tube itself is very narrow and long, perhaps 100 m, and has to be coiled (Fig. 4). Solutes are separated as in liquid chromatography, by their relative solubility in the gas and liquid phases. In gas-solid adsorption chromatography, solid particles coat the inside of the narrow tube. The solute vapors are separated by their relative attraction for the solid particles. In both cases, it is relative polarity that determines the distances between peaks.
