There will be no Fe(OH)₃ precipitate in a buffer solution that is 0.60 M CH₃COOH and 0.10 M CH₃COONa, if the solution is also made to be 0.001 M in Fe³⁺. For Fe(OH)₃, K_sp = 6.8 * 10^-36.

Question

Quizplus · Accepted Answer

The value of Ksp for Fe(OH)₃ is provided, but we also need to calculate the value of the ion product (Qsp) for Fe(OH)₃ in the buffer solution. Without this information, we cannot determine whether or not the solution is saturated with respect to Fe(OH)₃ and whether a precipitate will form.
