Solubility Product Constant (Ksp) is associated with any ionic compound, which measures how soluble the compound will be in a solvent.

Ksp

Concept #1: Solubility Product Constant (Ksp)

Example #1: Which substance is the most soluble?

a) AgCl Ksp = 1.6 x 10-10

b) MgCO3 Ksp = 3.5 x 10-8

c) CaSO4 Ksp = 7.1 x 10-5

d) CuS  Ksp = 8.5 x 10-45

Concept #2: Equilibrium Expressions

Example #2: Provide the equilibrium expression for calcium nitrate, Ca(NO3)2.

Concept #3: Calculating Ksp from Solubility

Concept #4: Calculating Solubility from Ksp

Practice: Determine the equilibrium expression of the barium nitride solid.

Practice: Manganese (V) hydroxide has a measured solubility of 3.4×10–5 M at 25ºC. Calculate its Ksp value.

Practice: The Ksp value for strontium fluoride, SrF2, is 7.9×10–10 at 25ºC. Calculate its solubility in g/L.
