Question
In 1L saturated solution of 
, 0.1 mole of 
is added. The resultant concentration of Ag in the solution is 
. The value of 
is
- 3
- 5
- 7
- 9
The correct answer is: 7
It is a case of simultaneous solubility of salts with a common ion. Here solubility product of 
is much greater than that of 
, it can be assumed that 
in solution comes mainly from 
.
