This is part of the HSC Chemistry course under the topic of Solution Equilibria.
In this post, we predict the formation of a precipitate given the standard reference values for Ksp.
An explanation of the “Rule of 100” used for Equilibrium calculations using an ICE table, to determine whether a reaction will form a precipitate.
An explanation of how to calculate Ksp from the molar solubility given, and how to predict the formation of a precipitate given the standard reference values for Ksp.
