MCQ

Which substance eliminates bromine from $KBr$ solution

A
${I_2}$
✓
$C{l_2}$
C
$HI$
D
$S{O_2}$

✓

Answer

Correct option: B.

$C{l_2}$

b
Chlorine is more reactive than bromine and it displaces bromine. If chlorine is added to a solution of potassium bromide, the bromine is replaced by the chlorine forming potassium chloride. Bromine is formed at the same time and can be detected by its colour.

$2 KBr + Cl _2 \rightarrow 2 KCI + Br _2$
