Find out number ionic compound(s) which is/are water insoluble at room temperature. BaSO4, AgNO3, Pb — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Analyze the chemical nature of iron(III) hydroxide. Fe(OH)3 is a weakly basic, non-amphoteric hydroxide precipitate. Step 2: Determine if it reacts with bases. Since it is not amphoteric, it does not react or dissolve in excess sodium hydroxide (NaOH) solution. Step 3: Because there is no chemical change or dissolution, the reaction is classified as no reaction (type D). Thus, the correct option is (d).
