What is 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
Tag: equilibrium constant
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

How to find the equilibrium constant and equilibrium concentrations for a reaction
Now it is time to introduce the concept of the equilibrium constant, Kc. Kc is basically a ratio – the
