How does Ksp determine solubility?

Question

Naomi Aronson · Accepted Answer

#K_(sp)# is a measure of solubility..........

See here and links....... The smaller the #K_(sp)# value the MORE INSOLUBLE the salt. #K_(sp)# values are quoted according to given conditions, i.e. typically #298*K#, and #1*atm#.

Mateo Aguilar · Answer

undefined The solubility of a compound is determined by its solubility product constant (Ksp). Ksp is the equilibrium constant for the dissolution of a sparingly soluble salt into its ions in a saturated solution. The higher the value of Ksp, the more soluble the compound is. If the concentration of ions in a solution exceeds the value of Ksp, the solution becomes supersaturated and precipitation occurs until equilibrium is restored. Therefore, Ksp can be used to predict whether a compound will dissolve or precipitate under certain conditions.

undefined The solubility of a compound is determined by its solubility product constant, Ksp. Ksp is the equilibrium constant for the dissolution of a sparingly soluble compound into its constituent ions in a saturated solution. The higher the value of Ksp, the more soluble the compound is, and vice versa. Ksp is calculated by multiplying the concentrations of the ions raised to their stoichiometric coefficients in the balanced equation for the dissolution reaction. When a solution reaches equilibrium with a solid solute, the rate of dissolution equals the rate of precipitation, resulting in a saturated solution where no more solid can dissolve. At this point, the concentration of the dissolved ions remains constant, and Ksp can be used to calculate the solubility of the compound.
