Colour of acidified K2Cr2O7 is not changed by : — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: In nitrogen trichloride (NCl3), nitrogen is more electronegative than chlorine. Hydrolysis of NCl3 yields ammonia (NH3) and hypochlorous acid (HOCl). Step 2: The nitrogen atom goes to ammonia (NH3), which is a basic gas and not an oxyacid. Step 3: Since the product containing the nitrogen atom is not an oxyacid, the reaction is categorized as type D, corresponding to option (d).
