Page 269 - The oxygen, both of the oxide and the acid of which the salt is composed, unites with the carbon, forming carbonic acid, while the sulphur and metal combine to form the new compound, the sulphuret} The sulphates in solution, are readily detected by muriate of baryta ; the muriate being decomposed by the sulphuric acid, an insoluble sulphate of baryta is formed, which falls to the bottom of the vessel in the form of a white powder.
Page 2 - BBOWN, of the said district, hath deposited in this office the title of a book, the right whereof he claims as author, in the words following, to wit : " Sertorius : or, the Roman Patriot.
Page 338 - A compound of these metals or their oxide may be dissolved in muriatic acid. If the iron is in a large proportion compared with the manganese, the following process may be adopted with advantage. To the cold solution, considerably diluted with water, and acidulated with muriatic acid, carbonate of soda is gradually added, and the liquid is briskly stirred with a glass rod during the effervescence, in order that it may become highly charged with carbonic acid. By neutralizing the solution in this...
Page 178 - The crowd from all sides soon collected to the number of several hundreds, some crying out for a husband, others for a parent or a son, and all deeply affected with an admixture of horror, anxiety, and grief.
Page 338 - ... acid with either of those alkalies. That this process should succeed, it is necessary that the iron be wholly in the state of peroxide, that the solution be exactly neutral, which may easily be insured, by the cautious use of ammonia, and that the reddish-brown coloured succinate of iron be washed with cold water. Of this succinate, well dried at a temperature of 212° F., 90 parts correspond to 40 of the peroxide.
Page 227 - This metal is of a whiter color than barium, and has a lustre like silver. When exposed to the air, it absorbs oxygen, and is converted into quicklime, and when thrown into water, the fluid is decomposed, its oxygen being absorbed, while hydrogen is given off, and a solution of lime remains CALCIUM AND OXYGEN.

As soon as the solution is thus rendered neutral, the hydrous alumina is collected on a filter, dried by exposure to a white heat, and quickly weighed after removal from the fire. Separation of iron and manganese. — A compound of these metals or their oxides may be dissolved in muriatic acid.
Page 264 - This is the red lead of commerce, and is extensively used as a pigment, and in the manufacture of flint glass. It is formed by heating litharge in a furnace so constructed that a current of air constantly passes over its surface. In this manner, the litharge which is chiefly a protoxide, is converted into a deutoxide, by absorbing another proportion of oxygen from the air. When red lead is heated to redness, it gives off pure oxygen, and is reconverted into the deutoxide. Peroxide of Lead. This is...
