A colourless crystalline Acid, HgC^H^Oj, eq. 150, obtained from the Acid Tartrate of Potash. In oblique rhombic prisms, of a strongly acid taste. Solubility, 10 in 8 of Water ; 1 in 8 of Eectified Spirit. Test.—100 grains neutralize 133 grains of Bicarbonate of Potash. 75 grains dissolved in Water require for neutralization 1000 grain-measures of volumetric solution of Soda. Its aqueous solution is not affected by Sulphuretted Hydrogen, and gives no precipitate with solution of Sulphate of Lime, or Oxalate of Ammonia—indicating absence of metallic contamination, Oxalic Acid, and Lime. If free from Lime it should leave no residue when burnt. It is distinguished from all other Acids by forming with strong solutions of neutral salts of Potash a crystalline precipitate (a bitartrate). Medicinal Properties. The same as Citric Acid, for which it was once substituted in saline mixtures. Dose.—10 to 30 grs. in Water. (In all Pharmacopoeias.) Ingompatibles.—Salts of Potash, of Lime, of Mercury, and of Lead, and the vegetable astringents. When Citric Acid was very dear, Tartaric Acid was much employed to make saline draughts, and it frequently perplexed the dispenser, for if the Bicarbonate of Potash was added to a solution of Tartaric Acid, Bitartrate was immediatelyformed, and was precTpitated whereas if the Tartaric Acid was added to the Potash Salt, it might be added to the point of saturation, and remain perfectly soluble. Contained in the tartrates of Alkalies, Antimony, and Iron. ACONITI FOLIA. ACONITE LEAVES. HERB. The fresh leaves and flowering tops of the perennial Aconiium Mpellus, gathered in July, when about one-third of the flowers are expanded, from plants cultivated m Britain.
