Write the equilibrium reactions on a scratch paper, calculate k from ksp and kf and determine the concentration of nh3 needed to form 0.060 m ag(nh3)2+, kf = 1.6 x 107; ksp agcl = 1.77 x10-10

1) The equilibrium constant for the required reaction is .

2) 1.2474 M the concentration of ammonia needed to form 0.060 M of complex.Explanation:

Solubility product of silver chloride:

..(1)

Formation constant of :

..(2)

Reactions solid silver chloride and liquid ammonia:

Expression of an equilibrium constant of the above reaction can be written as:

[AgCl] = solid = 1

(from 1 and 2)

The equilibrium constant for the required reaction is .

2)

Concentration of complex at equilibrium : = 0.060 M

Initaly

                       x                         0              0  

At equilibrium

         x- 2(0.060)                      0.060              0.060

x = 1.2474 M

1.2474 M the concentration of ammonia needed to form 0.060 M of complex.

3 hours because it is a decent distance.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
