Select the salt whose aqueous solution is not green : — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Identify starting materials: Iron(III) chloride (FeCl3) and sodium phosphate (Na3PO4) are both highly soluble in water. Step 2: Observe the double displacement: Upon mixing, the Fe3+ and PO4^3- ions combine to form a highly insoluble, buff-colored precipitate of iron(III) phosphate (FePO4↓). Step 3: Since a solid precipitate is formed from soluble starting materials, this is a precipitate formation reaction (type A).
