💡 Solution & Explanation

Step 1: Identify the reactants. Silver acetate, CH3COOAg↓, is a sparingly soluble precipitate, and HNO3 is a strong mineral acid. Step 2: Analyze the proton-transfer equilibrium. Nitric acid protonates the weakly basic acetate anion to form weakly dissociated acetic acid, shifting the solubility equilibrium to dissolve silver acetate into soluble silver ions (AgNO3). Step 3: Because the solid precipitate is dissolved by the acid, this is a precipitate dissolution reaction (type B). Thus, the correct option is (b).
