Deciding whether a precipitate will form
We can cause a sparingly soluble salt to precipitate out of solution if the product of the concentration of the
The common ion effect
Silver chloride is a sparingly soluble salt. AgCl(s) ⇌ Ag+(aq) + Cl–(aq) Ksp = [Ag+(aq)] [Cl–(aq)] = 2.0 x 10-10
What is the solubility product?
Many ionic compounds are sparingly soluble – a good example is barium sulphate which has a solubility of 1.05 x
Understanding the relationship between Kc and Kp
We can derive a value for the equilibrium constant in a gaseous equilibrium system either using partial pressures, Kp, or

Calculating Kp, the equilibrium constant, for a gaseous system.
For reversible reactions taking place in the gaseous phase it is more straightforward to think in terms of pressure rather
