PrecipitationLearning Goal:To understand the relationship between precipitation and the solubilityproduct and to be able to predict whether a substance will precipitate ornot.Precipitation is the formation of an insoluble substance. For the equationAB(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 theconcentrations of A and B gets above a certain level, the reaction willrespond by shifting left to decrease the concentrations of A and BThis critical level, Ksp. is a constant at a certain temperature. In this case,Q = [A+][B].where is the ion product. When Q> Kp. precipitation occurs until Qis equal to Kp.When Q≤ Ksp. a precipitate does not form.Part A - Calculate the value of QWhat is the value of Qwhen the solution contains 2.00 x 10 2M Ca²+ and 3.00 x 10 2M CrO²?Express your answer numerically.▸ View Available Hint(s)Q=IVD ΑΣΦSubmitPart CPart B Complete previous part(s)μÀValueSubmithWhat concentration of the lead ion, Pb²+, must be exceeded to precipitate PbCl₂ from a solution that is 1.00 x 10-2 M in the chloride ion, Cl?
