Frequent question: What is solubility constant Ksp?

The solubility product constant, Ksp​, is the equilibrium constant for a solid substance dissolving in an aqueous solution. It represents the level at which a solute dissolves in solution. The more soluble a substance is, the higher the Ksp value it has.

What is the relationship between KSP and 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.

What is KSP?

Ksp is called solubility product constant, or simply solubility product. In general, the solubility product of a compound represents the product of molar concentrations of ions raised to the power of their respective stoichiometric coefficients in the equilibrium reaction.

How do you find the solubility constant?

To do this, simply use the concentration of the common ion as the initial concentration. Example: Estimate the solubility of barium sulfate in a 0.020 M sodium sulfate solution. The solubility product constant for barium sulfate is 1.1 x 1010.

What does KSP 1 mean?

Solubility product constant is simplified equilibrium constant (Ksp) defined for equilibrium between a solids and its respective ions in a solution. Its value indicates the degree to which a compound dissociates in water. The higher the solubility product constant, the more soluble the compound.

The molar solubility of Al(OH)_(3) in 0.2 M NaOH solution is x xx 10^(-22)”mol/L”. Given that, solubility product of Al(OH)_(3)=2.4xx10^(-24).

What are the 4 factors affecting solubility?

Factors affecting solubility

  • Temperature. Basically, solubility increases with temperature. …
  • Polarity. In most cases solutes dissolve in solvents that have a similar polarity. …
  • Pressure. Solid and liquid solutes. …
  • Molecular size. …
  • Stirring increases the speed of dissolving.

What is KSP affected by?

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.

What is the solubility of AgCl?

The solubility of AgCl is 1.3 x 105 mol/L at 25oC.

What is solubility unit?

Water solubility is a measure of the amount of chemical substance that can dissolve in water at a specific temperature. The unit of solubility is generally in mg/L (milligrams per liter) or ppm (parts per million). You can often find it in the section 9 of a safety data sheet (SDS).
