What does it mean if q is greater than Ksp?

What does it mean if q is greater than Ksp?

The reaction quotient, Q, can be used to determine whether a precipitate will form with a given concentration of ions. 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.

What do higher Ksp values mean?

solubility product constant
The solubility product constant (Ksp) describes the equilibrium between a solid and its constituent ions in a solution. The value of the constant identifies the degree to which the compound can dissociate in water. The higher the Ksp, the more soluble the compound is.

Does a higher Ksp value always mean a higher solubility?

When comparing several salts at a given temperature, a higher Ksp value always means higher solubility. If they produce a different number of ions, they will have a different solubility amount.

What happens when Ksp is greater than QSP?

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. (i.e. to the left, ˆˆ precipitation forms) If Qsp = Ksp, then the system reaches equilibrium. (i.e. the solution is too dilute for a precipitate to form.)

What is the difference between Q and KSP How is this difference used?

The key difference between Ksp and Qsp is that Ksp indicates the solubility of a substance whereas Qsp indicates the current state of a solution. Solubility product quotient is the product of concentrations of ionic species in a solution at any time; before the saturation or after the solution is saturated.

Does a higher or lower KSP 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 …

Does a higher or lower Ksp precipitate first?

How do you compare values in Ksp?

The greater the Ksp the more ions are in solution, hence the greater the molar solubility. However, you can only directly compare salts that give equivalent numbers of ions in solution. For example, you can compare the Ksp’s of all salts with a 1:1 ion ratio like: AgBr, BaSO4 etc.

What does a lower Ksp value mean?

The larger the negative exponent the less soluble the compound is in solution. The larger the real value of the Ksp the more soluble the compound is in solution 2.5 x 10−3 > 2.5 x 10−6. Aug 18, 2016. Ksp refers to the solubility product .

What is the difference between the ion product Q and the solubility product Ksp?

The solubility product (Ksp) is used to calculate equilibrium concentrations of the ions in solution, whereas the ion product (Q) describes concentrations that are not necessarily at equilibrium.

How do you know if q is greater than K?

If K > Q, a reaction will proceed forward, converting reactants into products. If K < Q, the reaction will proceed in the reverse direction, converting products into reactants. If Q = K then the system is already at equilibrium.
