MCQ
Bromine is obtained on commercial scale from
- ACaliche
- ✓Carnellite
- CCommon salt
- DCryolite
✓
Answer
Correct option: B.
Carnellite
b
(b) Carnellite is $KCl.MgC{l_2}.6{H_2}O$. The mother liquor life after crystallisation of $KCl$ from carnellite contain about $0.25\%$ of bromine as $MgBr_2$ and $KBr$.
