Solubility

How do we use equilibrium constants to predict solubility?

[Jonathan Gong 2H]

The equilibrium constant for predicting solubility would be Ksp and can only be applied for solids dissolving in an aqueous solution. For a reaction such as aA(s) --> bB(aq) + cC(aq), Ksp can be determined by the equation Ksp = [B]^b * [C]^c. The higher the Ksp, the more soluble it is.

Equilibrium constants just describe how the reaction will be at equilibrium (the relative concentrations of the products and reactants), so you can use it to predict the behavior of any reaction.
