Question: when qsp is greater than ksp?
Answer: Ï Qsp must equal to or greater than Ksp for precipitation to occur. If Qsp < Ksp, then the reaction proceeds toward products. (i.e. to the right, ˆˆ no precipitation) If Qsp > Ksp, then the reaction proceeds to form reactants. If Qsp = Ksp, then the system reaches equilibrium.
