Sea is the greatest source of some halogens. Comment.
(N/A) Sea water contains chlorides,bromides,and iodides of $Na$,$K$,$Mg$,and $Ca$.
It primarily contains $NaCl$.
The deposits of dried-up sea beds contain sodium chloride and carnallite,$KCl \cdot MgCl_2 \cdot 6H_2O$.
Marine life also contains iodine in their systems.
For example,sea weeds contain up to $0.5\%$ iodine as sodium iodide.
Thus,the sea is the greatest source of halogens.
