Find out total number of coloured compound(s) from following : BaCO3, HgO, PbSO4, Ag2S, HgI2, PbO, C — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Identify the solubility of the starting materials. Manganese(II) nitrate and sodium hydroxide are highly soluble salts in water. Step 2: Observe the chemical transformation. The reaction results in the formation of insoluble manganese(II) hydroxide (Mn(OH)2↓). Step 3: Since a solid precipitate forms from the mixing of soluble ionic solutions, this is a precipitate formation reaction (type A). Thus, the correct option is (a).
