Folding chemistry
1. Magnesium chloride hexahydrate can be hydrolyzed by heating
When heated, water loss and hydrogen chloride partly generate magnesium oxide and basic magnesium chloride.
2. Magnesium and chlorine gas can be generated by electrolysis in the molten state of anhydrous magnesium chloride
MgCl2(melting)==electrolysis==Mg+Cl2↑
3. Formation of magnesium hydroxide precipitation in an alkaline environment.
Mg2++2OH-====Mg(OH)2↓
