Chapter 18, Problem 81IAE

Interpretation Introduction

Interpretation:

The K_f value of ${\left[{\text{CdI}}_{\text{4}}\right]}^{2-}$ should be calculated, where the solubility of CdCO₃(s) in 1.00 M KI(aq) is $1.2\times {10}^{-3}{\text{mol L}}^{-1}$.

Concept introduction:

The formation constant, K_f, of a complex ion is the equilibrium constant that defines the formation of a complex ion. Solubility product constant is defined as an equilibrium constant for salts which are slightly soluble in an aqueous solution.

It is the amount up to which a solute can dissolve in solution. Equilibrium constant, K, for a net ionic equation can calculated with use of solubility of each equilibrium or with use of other equilibrium constants.
