Magnesium chloride synthesis
- Product Name:Magnesium chloride

- Molecular Weight:95.21
Mg(OH)2(s)＋2HCl→MgCl2(aq)＋2H2O
It can also be prepared from MgCO3 by a similar reaction. Magnesium chloride is ionic and so will undergo electrolysis when it is molten. Electricity is carried by the movement of the ions within the melt and their discharge at the electrodes. However, solid magnesium chloride is a nonconductor of electricity because the ions are immobile.

Yield:-
Reaction Conditions:
with iodine in octane at 130; for 2 h;Inert atmosphere;Autoclave;
Steps:
An auto-clave was packed with Mg (0.5 g, 21 mmol), few small crystalsof iodine, octane (20 ml), and 1-chlorobutane (6.5 ml, 62 mmol)and heated at130C for 2 h. The resulting -MgCl2was washedwith octane.
