The equilibrium expression, Kd for the dissociation of the complex Zn(CN)42- is:
**Exponent is equal to the stoichiometric coefficient
First, we need to construct an ICE table for the dissociation of Zn(CN)42-
Next, we calculate for x, to determine the equilibrium concentration of Zn2+ and CN-
Kd = 2.1 × 1019
We can ignore the term "-x" in the denominator to simplify the equation, assuming x is a small value:
Calculate the equilibrium concentration of Zn2+ in a 0.30-M solution of Zn(CN)42−.
