Practice: Determine the equilibrium expression of the barium nitride solid.
Solubility Product Constant (Ksp) is associated with any ionic compound, which measures how soluble the compound will be in a solvent.
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.
