Which of the following metal hydroxide is not soluble in excess of NH3 solution ? — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Identify starting materials: Silver nitrate (AgNO3) and sodium carbonate (Na2CO3) are both highly soluble in water. Step 2: Observe the double displacement: Mixing these clear solutions leads to the combination of silver and carbonate ions to form a yellow-white precipitate of silver carbonate (Ag2CO3↓). Step 3: Since a solid precipitate forms from soluble starting materials, this is classified as a precipitate formation reaction (type A).
