Is KSP equal to concentration?

Ksq is defined in terms of activity rather than concentration because it is a measure of a concentration that depends on certain conditions such as temperature, pressure, and composition. It is influenced by surroundings. Ksp is used to describe the saturated solution of ionic compounds.

What is KSP equal to?

Ksp – Solubility product constant definition



The Ksp expression for a salt is the product of the concentrations of the ions, with each concentration raised to a power equal to the coefficient of that ion in the balanced equation for the solubility equilibrium.

Is concentration equal to solubility?

A saturated solution contains solute at a concentration equal to its solubility. A supersaturated solution is one in which a solute’s concentration exceeds its solubility—a nonequilibrium (unstable) condition that will result in solute precipitation when the solution is appropriately perturbed.

Is KSP the same as Q?

If Q < Ksp, no precipitate will form. 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.



Kf = [Ag(NH3)2+]
[Ag+][NH3]2

How do you find KSP expression?

Ksp=[M+][X−][MX(s)] , but MX(s) as A SOLID cannot express a concentration, and thus the expression simplifies to… Usually standard conditions are specified, because a hot solution can generally hold more solute than a cold one. have been measured for a host of insoluble, and semi-soluble ionic salts.

What is a high KSP value?

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 4 factors affect 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 S in solubility?

For example, sugar is a solute and water is a solvent. Solubility is defined as the maximum amount of solute that can be dissolved in a solvent at equilibrium. … Ksq is used to describe the saturated solution of ionic compounds.

What is the solubility of Al OH 3 in the presence of 0.2 M NaOH?

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).

Does increasing concentration increase solubility?

Conversely, when the partial pressure increases in such a situation, the concentration of gas in the liquid will increase as well; the solubility also increases.

How do you calculate Q?

We can calculate Q by writing out the equation using the balanced reaction and then using the given concentrations. If we compare Q to K, we can see that Q > K Q > K Q>KQ, is greater than, K.

Which KSP will precipitate first?

When two anions form slightly soluble compounds with the same cation, or when two cations form slightly soluble compounds with the same anion, the less soluble compound (usually, the compound with the smaller Ksp) generally precipitates first when we add a precipitating agent to a solution containing both anions (or …

What if Q is less than K?

If Qratio of products to reactants is less than that for the system at equilibrium—the concentration or the pressure of the reactants is greater than the concentration or pressure of the products.
