Solid lead (II) sulfate, PbSO4, is dissolved in water to form a solution with excess
Chapter 0, Problem 8(choose chapter or problem)
Solid lead (II) sulfate, PbSO4, is dissolved in water to form a solution with excess undissolved solute at the bottom of the container. Th e value of Ksp for lead sulfate is 2.5 3 1028 . a. How can you tell that this solution is saturated? b. Is the solution at equilibrium? How do you know? c. Write the chemical equation for the reversible change that is taking place. d. What is the equilibrium-constant equation for this equilibrium? e. What is the equilibrium concentration of each ion? f. Dissolving lead (II) sulfate is an endothermic change. Predict what will happen to the value of [Pb21] and [SO4 22] if the solution is heated. g. What would happen if you added more sulfate ions to the solution?
