Mixed with an equal measure of water, it usually throws down a white but scanty precipitate; it emits no vapour of nitrous acid. Diluted with 12 parts of water, it gives no yellow precipitate on the addition of hydro- sulphuric acid. 100 grains of this acid are saturated by 285 grains of crystallized carbonate of soda. Acidum Tannicum. Acid prepared from the Tannic Acid. gall-nut. ' Almost colourless. Dissolved in water, it is powerfully astringent. Prom a solution of isin- glass it throws down a certain white precipitate. In other respects its properties correspond with those of gallic acid, before named. Acidum Tartaricum. Acid prepared frombi- Tartaric Acid. tartrate of potash. Crystals. Free from colour; is entirely, or almost entirely, decomposed by fire ; is soluble in water. This solution throws down bitartrate of potash from any neutral salt of potash. Nothing is precipitated from the same solution by chloride of barium ; what is thrown down by acetate of lead is dissolved by nitric acid. 100 grains of this acid, dissolved in water, are saturated by 192 grains of crystals of carbonate of soda.
