Magnesium chloride in the sea water is reacted with lime (calcium oxide) to form the Mg 2+ and OHions, which precipitate into magnesium hydroxide salt. Another method is the electrolysis of fused magnesium chloride, which also gives Mg(OH) 2 in the same way.
Magnesium hydroxide is a kind of nonabsorption of antacid. This kind of drugs is not absorbed at all or only absorbed of a small amount by the digestive tract, thus having no systemic effects. Magnesium hydroxide has an effect similar to that of magnesium oxide. Its reaction with hydrochloric acid is slow and lasting effect.

The analytical methods reported for Ca and carbonate ions, summarized in the .
Magnesium hydroxide is the inorganic compound with the chemical formula Mg(OH) occurs in nature as the mineral is a white solid with low solubility in water (K sp = ×10 −12).Magnesium hydroxide is a common component of antacids, .
Lime Softening 1 Lime Softening . Chemical precipitation is one of the more common methods used to soften water. Chemicals normally used are lime (calcium hydroxide, Ca(OH) 2) and soda ash (sodium carbonate, Na 2CO 3). Lime is used to remove chemicals that cause carbonate hardness. Soda ash is used to remove chemicals that cause noncarbonate ...

Magnesium hydroxide is also used as a residual fueloil additive, an alkali drying agent in food, a colorretention agent, an ingredient of toothpaste and frozen desserts, a clarifier in sugar refining, and a neutralizing agent in the chemical industry 1). Magnesium hydroxide Mg(OH) 2 is categorized by the Food and Drug Administration (FDA ...
Magnesium hydroxide precipitates, while calcium hydroxide remains in solution. Magnesium hydroxide is filtered off and on heating readily forms the pure the oxide. Conversion to magnesium chloride is achieved by heating the oxide, mixed with carbon, in a stream of chlorine at a high temperature in an electric furnace (Figure 1).
