Salt of bromide when treated with HCl, KMnO₄, and CCl₄ gives brown layer of Br₂. In this reaction Br oxidized into Br₂ by? Answer: KMnO₄

KMnO₄ (Potassium permanganate): This is a strong oxidizing agent, capable of oxidizing bromide ions (Br-) to bromine gas (Br2). When added to a solution containing bromide ions, the purple color of KMnO₄ disappears, and a brown layer of bromine forms in the organic layer (if present).
