試題詳解

27. Silver acetate (AgC₂H₃O₂) is a sparingly soluble salt with K_sp = 1.9 × 10^-3. Consider a saturated solution in equilibrium with the solid salt. Compare the effects on the solubility of adding to the solution either the acid HNO3 or the base NH3.
(A) Either substance would decrease the solubility.
(B) NH3 would increase the solubility, but HNO₃ would decrease it.
(C) NH₃ would increase the solubility, but HNO₃ would have virtually no effect.
(D) Either substance would increase the solubility.
(E) NH₃ would decrease the solubility, but HNO₃ would increase it.
