. Solid solubility and a small amount of liquid material is defined as the temperature at double ester, 100 g of a solid material in a solvent (usually water) saturation mass can dissolve (at a certain temperature, 100 g solvent in a maximum amount of dissolved substance), represented by the letter S, Shandong double ester, the unit is "g / 100g water (g)". In the case of unspecified, generally it refers to a substance solubility solubility in water. 2. Gas solubility generally means that the gas (which is a standard pressure of 1 atm) was dissolved at a certain temperature in a number of volumes in the volume of the solvent. Also used "g / 100g solvent" for the unit (volume naturally also available). Application (l) by a beautiful woman substance known temperature corresponding solubility; (2) the substance is the temperature at which the solubility of the substance of the investigation; (3) the solubility of different substances at relatively the same temperature; compare the same substance at different temperatures solubility. (4) compare and determine the solubility of the substance by the sale of dual-degree temperature, methyl, and design the separation or purification of mixtures, such as purification of NaCl solvent by evaporation, separation of NaCl and NaNO? Available cooling crystallization. (5) can be determined at a temperature and quality of a substance in a saturated solution of the solute, solvent, solution ratio. (6) at a certain temperature determines the amount of solute dissolved in a solution of an amount of the solvent is formed in a saturated solution. (7) The solubility of the substance at 20 ° C to determine the solubility of the size of the material. (8) to determine the state of the solution (saturated and unsaturated).
