    aside to crystallize. Dry the crystals in bibulous paper, and then by moderate heat. Sodce Sesquicarbonas. Comp. Soda 38*55, carbonic acid 39 76, water of crystallization 21*69 parts; or 1 eq. soda=31*3+2, acid=44* 24 + 1 water=9, equiv.=84*54. (NaO,2C02, HO.) Prop. In minute crystals; less alkaline to the taste than the carbonate. Soluble in water, gives a slight brown to turmeric; neither chloride of platinum nor sulphate of magnesia, unless heat be applied, give any precipitate. The precipitate with chloride of barium is soluble in hydrochloric acid. 100 gr. of this salt, when added to diluted sul- phuric acid, give off 51*7 gr. of carbonic acid. A solution in 40 parts of water does not precipitate corrosive sublimate of an orange colour. Prop, and Use. The same as that of the carbonate. Dose. Gr. x. to 3ss. SOD^E CARBONAS. L. E. D. Carbonate of Soda. (The impure carbonate dissolved in water; the solution strained and crystallized.) Comp. Soda 20*92, carbonic acid 14-38, water of crystallization 64*7 parts; or 1 eq. of soda=31-3+l acid=22*l2+10 water=90, equiv.= 143 42. (NaO, CO*, 10 HO.) Prop. Colourless, transparent, soluble in water; renders turmeric brown. When supersaturated with hydrochloric acid, there is no pre- cipitate with chloride of barium. 100 gr. of carbonate of soda lose 62*5 gr. of water in a hot fire, and from the same quantity of the salt 15*28 gr. of carbonic acid are given off on the addition of dilute sul- phuric acid. Inodorous ; taste alkaline, but not acrid; crystals oblique octahedrons, efflorescent, requiring for their solution two parts of water at 60°; they undergo the watery fusion when exposed to heat. Oper. Antacid, deobstruent. Use. In dyspepsia, and acidities of the stomach, united with bitters ; and in scrofulous affections. Dose. Gr. x. to 3ss. twice or thrice a day. Incomp. Lime; acids, unless as an effervescing draught: hydrochlorate of ammonia, earthy and metallic salts. Off. Prep. Sodce Bicarbonas, D. Sodce Carbonas exsiccata, L. E. D. Sodce et Potassce Tartras, L. Ferri Sesquioxydum, L. Pilula Ferri Composites, L. Magnesice Carbonas, L. SODJE CARBONAS EXSICCATA. L. Sodas Carbonas Siccatum E. D. Dried Carbonate of Soda. (The carbonate made to undergo the watery fusion ; and, when dry, reduced to powder.) Comp. Soda 59*86, carbonic acid 40*14 parts; or 1 eq. soda=31*3+l acid =2212, equiv.=53*42. Oper. Antacid, lithontriptic. Use. In acidity of the stomach ; but chiefly in calculus in the kidneys ; and other affections of the urinary organs. Dose. Gr. v. to gr. xv. made into pills, with some aromatic powder and soap. SOD^: CARBONAS IMPURA. E. Sodas Carbonas, venale, Barilla, D. Impure Carbonate of Soda. (Prepared by nature in Egypt; arti- ficially from the incineration of marine plants ; and the decomposition of chloride of sodium.) Comp. Carbonate of soda, potassa, and chloride of sodium ; clay, and other earthy substances. Use. For preparing the pure carbonate. Off. Prep. Carbonas Sodce, E. D. SOD^ CARBONATIS LIQUOR. D. Sodas Aqua? effervescens, E. Water of Carbonate of Soda. {SodceBicarb. 3j., Aquce Oj. E. Sodcs Carbonatis cry stall. 3jss., Aquce distillates Oj. D. Dissolve and filter. The sp. gr. of the solutionis 1 026.) Prop, and Use. The same as those of the solid salt. SODiE MURiAS. E. Muriate of Soda. See Sodii Chloridum. Use. For preparing the exsiccated salt.
