- What is the molar solubility of lead(II) iodide in a 0.40 M solution of sodium iodide? Question 14 options: 0.40 M 8.8 x 10–8 1.5 x 10–3 1.9 x 10–4 1.8 x 10–8 Answer and Explainarrow_forwardLearning 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)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+A+ and B−B− ions gets above a certain level, the reaction will respond by shifting left to decrease the concentrations of A+A+ and B−B− ions. This critical level, KspKsp Q=[A+][B−]Q=[A+][B−]. where QQ is the ion product. When Q>KspQ>Ksp, precipitation occurs until QQ is equal to KspKsp When Q≤KspQ≤Ksp, a precipitate does not form.
