Q. Halides of alkaline earth metals from hydrates such as,

M g C l_{2} \cdot 6 H_{2} O, C a C l_{2} \cdot 6 H_{2} O, B a C l_{2} \cdot 2 H_{2} O

S r C l_{2} \cdot 2 H_{2} O

This shows that halides of group II elements :

M g {C l}_{2}

can be prepared by heating

M g {C l}_{2} \cdot 6 H_{2} O

M g C l_{2} \cdot 6 H_{2} O

on heating gives anhydrous

M g C l_{2}
