If Q is greater than Ksp, the solution is supersaturated and solid will precipitate until Q = Ksp. If Q = Ksp, the rate of dissolution is equal to the rate of precipitation; the solution is saturated, and no net change in the amount of dissolved solid will occur.
What if ionic product is greater than Ksp?
If solubility product is greater than the ionic product then, the solution is unsaturated and no precipitate will form by the addition of more solute. When Ksp< ionic product: If solubility product is less than the ionic product then the solution is super saturated and the excess of solute will precipitate immediately.
What is the difference between Ksp and ionic product?
Both ionic product and solubility product represent the product of the concentrations of the ions in the solution. … On the other hand, the term solubility product is applied only to a saturated solution in which there exists a dynamic equilibrium between the undissolved salt and the ions present in solution.
What happens when q is greater than Ksp?
If Q > Ksp, a precipitate will form. Note that precipitation may not happen immediately if Q is equal to or greater than Ksp. A solution could be supersaturated for some time until precipitation occurs. Fractional precipitation is a technique that separates ions from solution based on their different solubilities.
What does it mean if QSP is smaller than Ksp?
Ï Qsp must equal to or greater than Ksp for precipitation to occur. If Qsp < Ksp, then the reaction proceeds toward products. (i.e. to the right, ˆˆ no precipitation) If Qsp > Ksp, then the reaction proceeds to form reactants. If Qsp = Ksp, then the system reaches equilibrium.
What is the Ksp formula?
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 happens when ionic product is equal to solubility product?
IP = Ksp
When actual amount of ions equal to maximum amount of ions, the solution is saturated but there is no precipitation. Any addition of ions will result in precipitation since the saturated solution can no longer dissolve any more ions.
What is KW ionic product of water?
Water is a weak electrolyte and undergoes selfionistion to a small extent. “The product of concentrations of H+ and OH- ions in water at a particular temperature is known as ionic product of water.” It is designated as Kw. ions increases with increase in temperature.
What is ion product constant?
(noun) The result of multiplying the concentration of hydroxide times the concentration of hydronium ion, typically equal to 10−14.
How do you calculate ionic product?
When an addition of a acid or the base happens in the pure water, then the concentration of the ionic product concentration of the pure water can be calculated by using ionic product constant equation ([H+][OH–] = Kw), where the value of KW is constant at specific temperature but the concentration of the H+ and OH– …
What is application of solubility product?

What is Kip and KSP?
Kip= ionic product. Ksp= solubility product. Ksp> Kip, unsaturated ie no ppt forms. Ksp =Kip, saturated.
