Question

Bromine is commercially prepared from sea water by displacement reaction Cl2 + 2Br^-(aq.) -> 2Cl^-(aq.) + Br2. Br2 gas thus formed is dissolved into solution of Na2CO3 and then pure Br2 is obtained by treatment of the solution with :

Prashant Kotian · Accepted Answer

Correct answer: C. Step 1: Lead dioxide (PbO2) is a very strong oxidizing agent in which lead is in the +4 state. Step 2: Dilute nitric acid is not strong enough to reduce or react with lead dioxide, and PbO2 is completely insoluble in it. Step 3: Since no chemical reaction or dissolution occurs, this process is classified as no reaction (type D), corresponding to option (d).
