Consider a salt of a weak base and a weak acid such as ammonium cyanide. Both the and ions interact with water in an aqueous solution, but the net reaction can be considered as a proton transfer from to .

 

 

 

How do you show that the equilibrium constant for this reaction, Knet, is

 

 

 

where Ka is the ionization constant for the weak acid and Kb is the ionization constant for the weak base ?

Salts formed by reaction of a strong acid with a weak base areacidic, and salts formed by reaction of a weak acid with a strongbase are basic. This is due to the equilibrium the conjugate haswith its acid or base. For example, sodium bicaronate NaHCO3contains the conjugate of the weak acid H2CO3. The conjugate willreform the acid through the equilibrium

HCO3?(aq)+H2O(aq)?H2CO3(aq)+HO?(aq)

and, thus, acts as a weak base. A solution of NaHCO3yields abasic solution.

If a salt is derived from a weak acid and a weak base, the pH ofthe solution depends on the relative acid strength (Ka) ofthe cation and base strength (Kb) of the anion. IfKa>Kb, the solution of the salt is acidic. IfKa<Kb, it is basic. If Ka?Kb, it is neutral.

Given that

  • Ka for HCN is 4.9
