Solubility
|
Solubility is the property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a solid, liquid, or gaseous solvent to form a homogeneous solution of the solute in the solvent. The solubility of a substance fundamentally depends on the used solvent as well as on temperature and pressure. The extent of the solubility of a substance in a specific solvent is measured as the saturation concentration where adding more solute does not increase the concentration of the solution. Most often, the solvent is a liquid, which can be a pure substance or a mixture. One may also speak of solid solution, but rarely of solution in a gas (see vapor-liquid equilibrium instead). The extent of solubility ranges widely, from infinitely soluble (fully miscible ) such as ethanol in water, to poorly soluble, such as silver chloride in water. The term insoluble is often applied to poorly or very poorly soluble compounds. Under certain conditions, the equilibrium solubility can be exceeded to give a so-called supersaturated solution, which is metastable. Solubility is not to be confused with the ability to dissolve or liquefy a substance, because the solution might occur not only because of dissolution but also because of a chemical reaction. For example, zinc is insoluble in hydrochloric acid, but does dissolve in it by chemical reaction into zinc chloride and hydrogen, where zinc chloride is then soluble in hydrochloric acid. Solubility does not also depend on particle size or other kinetic factors; given enough time, even large particles will eventually dissolve. From Wikipedia under the

Asked by Riemu R - Sun Mar 1 03:33:54 2009 - Chemistry - 2 Answers - Comments A. Actually thare are many effects , but the direct effect is The common-ion effect which refers to the fact that solubility equilibria shift in accordance with Le Chatelier's Principle. for example Ca So4 Ca2+ + SO42- In this example, addition of sulfate ions to a saturated solution of calcium sulfate causes Ca SO4 to precipitate until the concentration of the ions in solution are such that they again satisfy the solubility product. (Addition of sulfate ions can, for example, be accomplished by adding a very soluble salt, such as Na2SO4.) another effect is The salt effect which refers to the fact that the presence of another salt, even though there is no common ion, has an effect on the ionic strength of the solution and hence on the… [cont.] Answered by Taha K - Sun Mar 1 03:50:08 2009 How to determine the solubility of pure form of a drug sample ?
Q. If I have a drug sample that contain impurities,what would be a simple laboratory method to determine the solubility of the pure form of the drug ? I am seeking details of a method that uses solubilty phase diagram. Asked by reenigne - Sat Dec 29 10:28:51 2007 - Chemistry - 1 Answers - Comments A. If the suspected impurities are at all soluble, there is no way you can find out the solubility of the pure material, without purifying the drug. Any physical measurements you carry out are bound to refer to the mixture that you have. Answered by Facts Matter - Sat Dec 29 12:04:55 2007 From Yahoo Answer Search: "solubility" |

 @ Buy.com Store: Buy.com Price: $112.89 USD • Compare Prices ► Condition: used A celebrated classic in the field updated and expanded to include the latest computerized calculation techniques In 1964, James N. Butler published a book in which he presented some simple graphical methods of performing acid-base, solubility, and complex formation equilibrium calculations. Today, both the book and these methods have become standard for generations of students and professionals in fields ranging from environmental science to analytical chemistry. Named a Citation Classic by the Science Citation Index in 1990, the book, Ionic Equilibrium, continues to be one of the most widely used texts on the subject. So why tamper with near-perfection by attempting a revision of that classic? The reason is simple the recent rapid development and wide availability of personal computers. In the revised Ionic Equilibrium, Dr. Butler updates his 1964 work by abandoning the slide rule and graph paper for the PC spreadsheet. He also expands the original coverage with extensive material on basic principles and recent research. The first part of Ionic Equilibrium is devoted to the fundamentals of acid-base, solubility, and complex formation equilibria. In the second part, the author discusses oxidation-reduc tion equilibria, develops the principles of carbon dioxide equilibria, presents case studies demonstrating the ways in which carbon dioxide equilibria are used in physiology and oceanography, and explores the possibility of a p H scale for brines. The concluding chapter, written by David R. Cogley, gives examples of general computer programs that are capable of performing equilibrium calculations on systems of many components. Replete with real-world examples, detailsof important calculations, and practical problems, Ionic Equilibrium is an ideal course text for students of environmental chemistry, engineering, or health; analytical chemistry; oceanography; geochemistry; biochemistry; physical chemistry; and clinical chemistry. It is also a valuable working resource for professionals in those fields as well as industrial chemists involved with solution chemistry.  @ Target Store: Target Price: $23.84 USD • Compare Prices ► Condition: new health Concern: Heart Health. pieces: 300. manufacturer Suggested Age: 18 Years And Up.
