Which of the following statements are true about sodium thiosulphate, Na2S2O3? — p Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: Ozone (O3) is a powerful oxidizing agent. Step 2: When potassium ferrocyanide, K4[Fe(CN)6] (where Fe is in the +2 oxidation state), reacts with ozone in aqueous solution, Fe(II) is oxidized to Fe(III) in potassium ferricyanide, K3[Fe(CN)6]. Step 3: The reaction is: 2K4[Fe(CN)6] + O3 + H2O -> 2K3[Fe(CN)6] + 2KOH + O2. Thus, the product is K3[Fe(CN)6], matching option (c).
