WebThe Henry’s law constant H is a proportionality coefficient describing the distribution between these phases. It can be defined either as the ratio Q l /Q g (related to solubility) or its inverse Q g /Q l (related to volatility). Both choices are in common use, and the resulting Henry’s law constants are reciprocals of each other.

A solubility equilibrium exists when a chemical compound in the solid state is in chemical equilibrium with a solution containing the compound. This type of equilibrium is an example of dynamic equilibrium in that some individual molecules migrate between the solid and solution phases such that the rates of dissolution and precipitation are equal to one another. When equilibrium is established and the solid has not all dissolved, the solution is said to be saturated… WebThe solubility of a solute in a particular solvent is the maximum concentration that may be achieved under given conditions when the dissolution process is at equilibrium.

Molar solubility – the solubility of a substance, in this case a slightly soluble ionic compound, expressed as the amount of solute (moles) dissolved in one liter … mcman familyWebThis equation suggests that the product of the equilibrium concentrations of the Ag + and Cl - ions in this solution is equal to a constant. Since this constant is proportional to the solubility of the salt, it is called the solubility product equilibrium constant for the reaction, or Ksp. Ksp = [Ag + ] [Cl -] mcmaniacs vintage

"WebThe equilibrium constant, the Ksp, is no more than the product of the ions in solution. (Remember, solids do not appear in equilibrium expressions.) For a saturated solution of AgCl, the equation would be: AgCl(s) R Ag+(aq) + Cl−(aq) The solubility product expression would be: Ksp = [Ag +][Cl−] " - R constant solubility

Solubility is defined for specific phases. For example, the solubility of aragonite and calcite in water are expected to differ, even though they are both polymorphs of calcium carbonate and have the same chemical formula. The solubility of one substance in another is determined by the balance of intermolecular forces between the solvent and solute, and the entropy change th… WebSolubility product constants are used to describe saturated solutions of ionic compounds of relatively low solubility. A saturated solution is in a state of dynamic equilibrium between the dissolved, dissociated, ionic compound and the undissolved solid. MxAy(s) --> …
