Question

A solution of potassium bromide is treated with each of the following. Which one would liberate bromine ? (A) Hydrogen iodide (B) Sulphur dioxide (C) Chlorine (D) Iodine

Tardigrade Admin · Accepted Answer

Chlorine is good oxidising agent than bromine, so, Cl2 oxidise Br- to bromine. 2KBr + CI2 longrightarrow 2KCI + Br2

Q. A solution of potassium bromide is treated with each of the following. Which one would liberate bromine ?

Hydrogen iodide

Sulphur dioxide

Chlorine

Iodine

Chlorine is good oxidising agent than bromine, so, $C l_{2}$ oxidise $B r^{-}$ to bromine.
$2 K B r + C I_{2} ⟶ 2 K C I + B r_{2}$
