Sometimes equilibria for complex ions are described in terms of dissociation constants, K_d. For the complex ion AlF₆³⁻ the dissociation reaction is:

AlF₆³⁻ ⇌ Al³⁺ + 6F⁻ and K_d = [Al³⁺][F⁻]⁶ divided by [AlF₆³⁻] =2×10⁻²⁴

Calculate the value of the formation constant, K_f, for AlF₆³⁻.

Be sure to answer all parts. Commercial silver-plating operations frequently use a solution containing the complex Ag+ ion. Because the formation constant (Kf) is quite large, this procedure ensures that the free Ag+ concentration in solution is low for uniform electrodeposition. In one process, a chemist added 9.0 L of 5.0 M NaCN to 90.0 L of 0.17 M AgNO3. Calculate the concentration of free Ag+ ions at equilibrium. See your textbook for Kf values. × 10 M (Enter your...
