Preparation of Magnesium hydroxide
When a solution of magnesium salts is combined with alkaline water it instigates precipitation of solid magnesium hydroxide. The reaction is as follows:
Mg2+ + 2 OH− → Mg(OH)2
Commercially it is produced by treating lime and seawater. Approximately one ton of magnesium hydroxide is obtained from 600 m3 of seawater. Calcium hydroxide is more soluble in magnesium hydroxide therefore Mg(OH)2 precipitates as a solid. The reaction is as follows:
MgO + H2O → Mg(OH)2
