Consider three P, Q, R salts among them P and Q salts have different cations and also have different — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Identify the state of reactants and products. Pb(NO3)2 and NaOH are highly soluble in water, forming a clear solution. Step 2: Observe the chemical change. The reaction leads to the formation of insoluble lead(II) hydroxide, denoted by the downward arrow (Pb(OH)2↓). Step 3: Since a precipitate is formed from soluble starting materials, this reaction belongs to type A (precipitate formation reaction). Thus, the correct option is (a).
