aqueous solution - Will this reaction form magnesium …
$\begingroup$ Calcium is also expensive and difficult to handle as a metal. It is prone to oxidation, and it does not form a protective layer like beryllium or magnesium itself. Magnesium is sometimes made by a coination of processes, whereby the oxide is reacted with both carbon and chlorine to make the chloride which is then electrolyzed. $\endgroup$ – Oscar Lanzi May 12 ''17 at 15:10
