    cyanie acid, sulphuric acid, boracic acid, phosphoric acid, oxalic acid, hydrofluoric acid, silicic acid, hydrochloric acid, hydrobromie acid, hydriodic acid, nitric acid, chloric acid. 5. Oraantco Actps.—Tartaric acid, citric acid, malic acid, benzoic acid, succinic acid, tannic acid, gallic acid, uric acid, acetic acid, formic acid. 6. Each of these bases and acids is A SOLID, A LIQUID, or A GAS; in whicheyer state the base or acid exists, it must be soluble or insoluble in water. If the base or acid is A SoLID, and insoluble, it will, on being sepa- rated from any of its soluble compounds, float in or upon the water or else fall to the bottom; in either case it is called a precipitate; if it is soluble, it will remain dissolved when separated from any of its soluble com- pounds. If it is a L1gurp, and insoluble, it will float upon the waterif lighter than that liquid, and if heavier, the water will float upon it; if it is soluble, it will mix with the water. If it is a @as and insoluble, it will, on being separated from any of its soluble or insoluble compounds, escape into the air; if it is soluble, it will remain dissolved in the water, if there is sufficient for its solution—if there is not sufficient, the excess will escape into the air; if it is dissolved by the water, it will most probably escape when the liquid is warmed, being expelled by the heat. 7. The bases, with the exception of ammonia, are all solid and non-volatile bodies. | Potash, soda,’ ammonia, baryta, strontia, and lime, are soluble in water; the rest of the bases are insoluble in that'liquid. The compound pro- duced by the union of a base with-an acid is: called a salt. Many of the salts of the insoluble bases are soluble in water. The salts of the gaseous base, ammonia, and the salts of the gaseous acids, are solids; some of these solid salts are soluble, some are insoluble, in water.
