The Common Ion Effect is a phenomenon in solution equilibria as part of HSC Chemistry's Module 5: Equilibrium and Acid Reactions. Calculations involving the common ion effect is included.

Syllabus Dotpoints
* conduct an investigation to determine solubility rules, and predict and analyse the composition of
substances when two ionic solutions are mixed, for example:
– potassium chloride and silver nitrate
– potassium iodide and lead nitrate
– sodium sulfate and barium nitrate (ACSCH065)
* derive equilibrium expressions for saturated solutions in terms of Ksp and calculate the solubility of an ionic substance from its Ksp value
* predict the formation of a precipitate given the standard reference values for Ksp
