What is the value of Q when the SrCrO4 solution contains 2.00×10−2 M Sr2+ and 1.50×10−3M CrO42−? Calculate the value of Q.
SrCrO4 <--> Sr+2 and CrO4-2
Q = [Sr+2][CrO4-2]
Q = (2*10^-2)(1.5*10^-3) = 3*10^-5
Q = 3*10^-5

Strontium chromate, SrCrO4, has a Ksp value of 4.00×10−5 . What happens when strontium and chromate solutions are mixed to give 2.00×10−2 M Sr2+ and 1.50×10−3 M CrO42−?
Learning Goal: To understand the relationship between precipitation and the solubility product and to be able to predict whether a substance will precipitate or not. Precipitation is the formation of an insoluble substance. For the equation AB(s)⇌A+(aq)+B−(aq), precipitation represents a shift to the left and the production of a solid. From Le Châtelier's principle, we know that when the product of the concentrations of A+ and B− gets above a certain level, the reaction will respond by shifting left to...
