Addition of Na2CO3 to a solution of an oxide in water produces CO2. This experiment indicates that : — s Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: Electrolysis of brine (aqueous NaCl) yields chlorine gas (Cl2) at the anode, and hydrogen gas (H2) and sodium hydroxide (NaOH) at the cathode. Step 2: If the products are mixed, chlorine gas reacts with cold, dilute sodium hydroxide solution to produce sodium chloride, sodium hypochlorite, and water: 2NaOH + Cl2 -> NaCl + NaOCl + H2O. Step 3: Because the chlorine gas (Cl2) is completely consumed in this reaction to form NaCl and NaOCl, Cl2 is not obtained as a product after mixing. Thus, the correct option is (d).
