Do soluble salts have KSP?

These salts have a Solubility Product Constant, Ksp. The solubility of salts (saturated solution) are often expressed in one or more of the following units with the temperature also specified: mol/L (molar solubility) g/L , g/mL, g/100 mL or mg/L (Note that these are NOT densities.)

What is KSP of sparingly soluble salt?

The Ksp (25^oC) of sparingly soluble salt XY2 is 3.56 × 10^-5 mol^3 L^-3 and 30^oC , the vapour pressure of its saturated solution in water in 31.78 mm of Hg.

What factors affect KSP?

What factors affect the value of Ksp?

• The common-ion effect (the presence of a common ion lowers the value of Ksp).
• The diverse-ion effect (if the ions of the solutes are uncommon, the value of Ksp will be high).
• The presence of ion-pairs.

How does KSP relate to solubility?

Ksp (Solubility product constant) is the equilibrium between a solid and its respective ions in a solution. The value of the constant identifies the degree of which the compound can dissociate in water. For example the higher the Ksp the more soluble the compound is.

How does KSP affect precipitation?

1) If Solubility product is larger than the ionic product then no precipitate will form on adding more solute because unsaturated solution is formed. 2) If Solubility product is smaller than the ionic product then excess solute will precipitate out because of the formation of super saturated solution.

What are examples of sparingly soluble salts?

Sparingly Soluble Salt: A certain substance like AgCl, PbSO4, BaSO4 etc. have negligible solubility in water at ordinary temperature. Such substances which are practically insoluble in water are called as sparingly soluble electrolytes.

Does KSP depend on solvent?

K s p represents how much of the solute will dissolve in solution. The value of K s p varies depending on the solute. The more soluble a substance is, the higher its K s p chemistry value.

What is the difference between solubility and solubility product constant?

The difference between solubility and solubility product is that solubility the describes the dissolution of a substance in a solvent whereas the solubility product describes the mathematical product of the dissolved ion concentrations raised to the power of their stoichiometric coefficients.
