Silver chloride is a sparingly soluble salt. AgCl(s) ⇌ Ag+(aq) + Cl–(aq) Ksp = [Ag+(aq)] [Cl–(aq)] = 2.0 x 10-10
Many ionic compounds are sparingly soluble – a good example is barium sulphate which has a solubility of 1.05 x
We can derive a value for the equilibrium constant in a gaseous equilibrium system either using partial pressures, Kp, or
Continue readingUnderstanding the relationship between Kc and Kp
For reversible reactions taking place in the gaseous phase it is more straightforward to think in terms of pressure rather
Continue readingCalculating Kp, the equilibrium constant, for a gaseous system.
Now it is time to introduce the concept of the equilibrium constant, Kc. Kc is basically a ratio – the
