Not illustrated. 1912 Excerpt: ...dioxide is passed. The hydroxide is dissolved as acid carbonate. The clear solution is then heated rapidly to 70, and afterwards more gradually to the boiling-point. The precipitated magnesia alba is filtered off and dried on plates heated by steam. If necessary, the original mother-liquor may first be freed from organic matter by treatment with alum. Magnesia alba is almost insoluble in water, but dissolves readily in solutions of ammonium j salts owing to the formation of soluble double salts of magnesium and ammonium and ammonium carbonate. Magnesium ammonium carbonate MgC03-(NH1)lCOs,4HilO separates in rhombohedral crystals from a mixture of cold aqueous solutions of magnesium sulphate or chloride and excess of ammonium carbonate and free ammonia. Magnesium potassium carbonate MgCO3-K, CO, 4H., O is obtained in small rhombic prisms when mag-nesia alba is digested with a solution of acid potassium carbonate for 15 hours at 60-70. A salt of the composition MgCO3-HKC03,4H, O is obtained in largo crystals from a cold aqueous mixture of magnesium chloride or nitrate with excess of acid potassium carbonate. Engcl (Compt. rend. 100, 1224) obtained the same suit by decomposing a sohition of the acid magnesium carbonate with potassium bicarbonate, and also by direct action of the potassium bicarbonate 1 upon normal magnesium carbonate. Magnesium sodium carbonate MgCO, -Na, rO:, is similarly obtained in small anhydrous crystals by digesting magnesia alba with sodium bicarbonate. Magnesium nitride Mg3N, . Magnesium combines directly with nitrogen when heated to redness. It is also one of the products of the incomplete combustion of magnesium in air. It is a greenish-yellow amorphous body which decomposes slowly in humid air, yielding ammonia and magnesia, rapidly in
