Not illustrated. 1906 Excerpt: ...crystallization of sodium chloride from seawater. At the present time large quantities are made as a by-product in the manufacture of carbon dioxide for use in mineral waters. Magnesite is used to furnish this gas and sulphuric acid is used to effect its liberation, as follows: MgCOa HaS04 MgSO- CO- HuO. Magnesite. Sulphuric Magnesium Carbon Water. Acid. Sulphate. Dioxide. After the escape of carbon dioxide, the residue is dissolved in hot water, neutralized with magnesite, some barium sulphide added, and the mixture allowed to stand for some time in order to separate iron; finally, the clear liquid is concentrated and allowed to crystallize. The Abraumsalz above mentioned is also employed as a source of magnesium sulphate. This salt is exposed to a damp atmosphere, or suspended in baskets over open evaporators, so that it is brought in contact with the ascending steam; by this means the very soluble magnesium and sodium chlorides are dissolved, while the kieserite remains behind. Kieserite is not easily dissolved by water, but on contact with that liquid it disintegrates and is converted into Epsom salt, containing 7 molecules of water; in this form it is dissolved and recrystallized. Properties.--Magnesium sulphate crystallizes from water in colorless, rhombic prisms, or in small acicular crystals; the latter form is obtained by allowing the crystallization to take place from hot concentrated solutions. The salt is without odor, and has a cooling, saline, bitter taste; the crystals slowly effloresce in dry air. It is soluble in 0.85 parts of water at 25, and in 0.13 part of boiling water; insoluble in alcohol. When heated to 520 the salt loses 1 molecule of water, from this temperature up to 1320 it loses 5 additional molecules, and at 2000 to 2...
