Which of the following compound is completely water soluble ? — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Observe that lead(II) nitrate, Pb(NO3)2, is a soluble salt, and sulfuric acid, H2SO4, is a strong soluble mineral acid. Step 2: Mixing these reactants results in the formation of insoluble lead(II) sulfate, PbSO4↓, which precipitates out of the solution. Step 3: Consequently, this is classified as a precipitate formation reaction (type A), matching option (a).
