Question
Which of the following affects the value of the solubility product, Ksp, of silver sulphide when it is precipitated by passing hydrogen sulphide into aqueous silver nitrate? 2AgNO₃(aq) + H₂S (g) → Ag₂S (s) + 2HNO₃ (aq)
Correct Answer
Option D is the correct answer.
Detailed Explanation
The solubility product (Ksp) is an equilibrium constant. Equilibrium constants are only affected by changes in temperature. Factors like concentration, addition of other ions, or changes in pressure do not change the value of Ksp (though they can shift the equilibrium position).
Hint
Ksp is a specific type of equilibrium constant. What are the only factors that change an equilibrium constant's value?
