For everyone out there who think i hate you... I don't. Those of you who hate me, oh well hate me, hurt me, do whatever you want. those of you who have hurt me i wanna thank you, you made me into the person i am today. I would rather help others be happy than pay attention to me and use my own advice to make myself happy. Everyone out there who thinks they know me... you don't know the first part about me... and for everyone i don't know... Your terrific the way you are, don't change for anyone... btw if anyone wants to talk im bored...and Free points

Answerthis solution will not form a precipitateexplanationsolubility equilbrium:         pbf₂(s)  ⇄ pb²⁺(aq) + 2 f⁻(aq)the solubility product expression is    (we exclude solids from the equilibrium expression).now suppose we have the trial ion product q, which we can define as    then, we can interpret  q as the product of the concentration of the ions that we have and ksp as the product of the ion concentrations that are needed to form a saturated solution.if q > ksp, then that implies that there will be a surplus of ions that exceed the amount that is required to form a saturated solution. a precipitate will then form (the precipitate continually  forms until the surplus ions are removed and q is decreased to ksp's value).if q = ksp, the saturated solution that forms is barely saturated and the precipitate will be minimal.if q < ksp, then the ion concentration will not be enough to form a saturated solution (so no precipitate).using our information, we calculate the trial ion product:     since q = 2.7  × 10⁻⁸ < ksp =  4  ×  10⁻⁸, a precipitate will not form.
