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.
