What is the solubility product constant KSP of NaCl?
Sodium chloride has a solubility of about 360 g per liter of water at 25°C. Salts of alkali metals tend to be quite soluble. On the other end of the spectrum, the solubility of zinc hydroxide is only 4.2 × 10 -4 g/L of water at the same temperature.
How does KSP determine solubility?
The solubility product constant (Ksp) describes the equilibrium between a solid and its constituent ions in a solution. The value of the constant identifies the degree to which the compound can dissociate in water. The higher the Ksp, the more soluble the compound is.
What is a solubility product constant How are such constants determined?
Kc = [My+]x[Ax-]y. Since the equilibrium constant refers to the product of the concentration of the ions that are present in a saturated solution of an ionic compound, it is given the name solubility product constant, and given the symbol Ksp.
What can be determined if Q The ion product is compared to KSP The solubility product constant?
The solubility product (Ksp) is used to calculate equilibrium concentrations of the ions in solution, whereas the ion product (Q) describes concentrations that are not necessarily at equilibrium. Comparing Q and Ksp enables us to determine whether a precipitate will form when solutions of two soluble salts are mixed.
What does KSP depend on?
The solubility product is a kind of equilibrium constant and its value depends on temperature. Ksp usually increases with an increase in temperature due to increased solubility.
How do you determine solubility experimentally?
Slowly add known amounts of the solute until no more will dissolve, even after vigourous and prolonged stirring. If you do this experiment at 20 °C with water as the solvent and sodium bromide as the solute, you will find that 90.8 g of the salt dissolve in 100 mL water.
Is KSP molar solubility?
A substance’s solubility product (Ksp) is the ratio of concentrations at equilibrium. Molar solubility, which is directly related to the solubility product, is the number of moles of the solute that can be dissolved per liter of solution before the solution becomes saturated.
What happens if Q Ksp?
The reaction quotient, Q, can be used to determine whether a precipitate will form with a given concentration of ions. If Q = Ksp, a precipitate will form. If Q > Ksp, a precipitate will form. Note that precipitation may not happen immediately if Q is equal to or greater than Ksp.
What is the difference between Q and Ksp?
Ksp is defined as a saturated solution which has equilibrium between ionic species and a solid precipitate (the moment at which the formation of a precipitate has begun). The difference between Ksp and Qsp is that Ksp is the solubility product constant whereas Qsp is the solubility product quotient.
