Calculate the value of the equilibrium constant, K c , for the reaction AgCl ( s ) + Cl − ( aq ) − ⇀ ↽ − AgCl − 2 ( aq ) K c = ? The solubility product constant, K sp , for AgCl is 1.77 × 10 − 10 and the overall formation constant, K f ( β 2 ), for AgCl − 2 is 1.8 × 10 5 .

The equilibrium constant is  Kc  

Explanation:

      The equation for the formation of can also be defined as  

Now the formation constant is mathematically represented as

                for the formation of

Substituting parameters
