Consider a saturated aqueous solution of Ag2S that contains some excess solid Ag2S at the bottom. Which of the following statements is/are true? Adding AgNO3 to the solution will cause more Ag2S to dissolve. Adding some more Ag2S to the solution will cause more Ag2S to dissolve. Adding some water to the solution will cause more Ag2S to dissolve.

Adding some water to the solution will cause more to dissolve is a true statement.

Explanation:

Solubility equilibrium of is given as follows-

                             

Solubility product of ,

Concentration of increases when is added into solution. But value of is constant at a certain temperature. Hence to keep constant, some will combine with to produce more . So, adding to the solution will cause more to dissolve is a false statement. does not depend on concentration of . So, adding some more   to the solution will cause more to dissolve is a false statement.Addition of water will increase the volume of solution. Hence concentration of both and will decrease. So, more will dissolve to produce more and to keep constant. Hence, adding some water to the solution will cause more to dissolve is a true statement.
