When does a precipitate form from mixing two salt solutions?
A.When Q > Ksp
B.When Q < Ksp
C.When Q = Ksp
D.Whenever any ions are present
Explanation
Core Concept
The ion product exceeding Ksp means the solution is supersaturated with respect to that solid, so it precipitates until Q falls to Ksp.
Correct Answer
AWhen Q > Ksp
