Q. On strong heating $MgCl_{2}\ .\ 6H_{2}O$, the product obtained is
A) $MgCl_{2}$
B) $MgO$
C) $MgCl_{2}\ .\ 2H_{2}O$
D) $MgCl_{2}\ .\ 4H_{2}O$
Explanation
(b)
On strong heating, $MgCl_{2}\ .\ 6H_{2}O\$is hydrolysed by its own water of crystallisation.
$\ \ \ \ \ \ \ \ \ \ \ MgCl_{2}\ .\ 6H_{2}O\ \overset{\ \ \ \ \ \mathrm{\Delta}\ \ \ \ \ }{\rightarrow}\ MgO + 2HCl + 2H_{2}O$
