Answer: When HNO3 is added to a saturated solution of silver acetate, it will react with the acetate anions to form nitric acid and acetic acid. This will shift the equilibrium of the solubility reaction to the right, according to Le Chatelier's principle, resulting in an increase in the solubility of silver acetate.
AgC2H3O2(s) ⇌ Ag+(aq) + C2H3O2-(aq)
Adding NH3 to the saturated solution of silver acetate will react with the silver ions to form the complex ion Ag(NH3)2+. This will remove the silver ions from the solution, thus decreasing the concentration of Ag+ in the solution. According to Le Chatelier's principle, the equilibrium of the solubility reaction will shift to the left to compensate for the decrease in Ag+, resulting in a decrease in the solubility of silver acetate.
Ag+(aq) + 2NH3(aq) ⇌ Ag(NH3)2+(aq)
Therefore, the addition of HNO3 will increase the solubility of silver acetate, while the addition of NH3 will decrease the solubility of silver acetate.
