Silver iodide, solubility product constant

What would you expect to happen if 1 g of finely powdered silver iodide were stirred into a 1 F solution of sodium chloride The solubility-product constants are given in Table 22-1. 

Suppose you wish to determine the solubility of silver iodide (Agl) in mol/L at 298 K. The equilibrium equation and solubility product constant expression are as follows. 

EXAMPLE 7-6 Calculate the solubility of silver iodide in 0.01 M ammonia, if the solubility product of silver iodide is 9 x 10 and the logarithms of the successive formation constants of the silver-ammonia complexes are 3.2 and 3.8. 

Since there are two singly charged ions both in the numerator and in the denominator of this equilibrium concentration quotient and thi ionic concentration never exceeds 0.1 mole 1 , we assume that th. value of is equal, within about 10%, to that of the (thermodynamic < equilibrium constant for the reaction. Dmding this constant by thf solubility product of silver iodide, we obtain the equilibrium constant K - Q s ...
