What is solubility product, and how does it predict whether a precipitate will form?
Original Khojo Papers practice question — not from a past board paper.
Answer
The solubility product is the equilibrium constant for the dissolution of a sparingly soluble salt, the product of the molar concentrations of its ions each raised to the power of its coefficient. If the ionic product in a solution exceeds the solubility product a precipitate forms; if it is less, none forms and any solid present dissolves.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
This is the principle on which selective precipitation in analysis rests.
