Which expression represents the solubility product of lead (ⅠⅠ) chloride?
Correct answer: B. (PB+2)(2CL-).
- A. (PB+2)2(CL-).
- B. (PB+2)(2CL-).
- C. (PB+2)(CL-2).
- D. (PB)(CL).
Explanation
The solubility product constant (Ksp) of lead(II) chloride (PbCl2) is approximately 1.6 x 10^(-5) at 25°C. This value indicates the equilibrium constant for the dissolution of solid lead(II) chloride into its constituent ions in a saturated solution. The equation representing the dissolution of PbCl2 is: PbCl2(s) ⇌ Pb²⁺(aq) + 2 Cl⁻(aq) The Ksp expression for this equilibrium is: Ksp = [Pb²⁺][Cl⁻]² Where [Pb²⁺] represents the concentration of lead(II) ions in the solution and [Cl⁻] represents the concentration of chloride ions in the solution. Keep in mind that the solubility product constant may vary slightly depending on temperature and conditions.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
