First list all the insoluble magnesium bases

$M {g (O H)}_{2} + 2 H C l \to M g C l_{2} + 2 H_{2} O$ $Mg(OH)_2 + 2HCl rarr MgCl_2 + 2H_2O$

$M g O (s) + 2 H C l \to M g C l_{2} + H_{2} O (l)$ $MgO(s) + 2HCl rarr MgCl_2 + H_2O(l)$

$M g C O_{3} + 2 H C l \to M g C l_{2} + C O_{2} + H_{2} O$ $MgCO_3 + 2HCl rarr MgCl_2 + CO_2 + H_2O$

$M g S + 2 H C l \to M g C l_{2} + H_{2} S$ $MgS + 2HCl rarr MgCl_2 + H_2S$

$M g S O_{3} + 2 H C l \to M g C l_{2} + H_{2} O + S O_{2}$ $MgSO_3 + 2HCl rarr MgCl_2 + H_2O + SO_2$

$2 HCl + {MgSiO}_{3} \to {MgCl}_{2} + {SiO}_{2} + H_{2} O ({at 90}^{\circ} C)$ $2"HCl" + "MgSiO"_3 rarr "MgCl"_2 + "SiO"_2 + "H"_2"O"("at 90"^@"C")$
