Question:

When lead iodate, Pb(IO3)2, is added to water, a small amount dissolves. If measurements at 25 °C show that the Pb2+ concentration is 4.5 × 10-5 M, calculate the value of Ksp for Pb(IO3)2.
Strategy

Solubility equilibria are solved by the same approach used for all equilibria. We will write the chemical equation, iCe table, and algebraic expression for the equilibrium constant; substitute numerical values from the iCe table; and solve.
