Página 258 - This is strikingly shown in an alloy called the " fusible metal," which is composed of 8 parts of bismuth, 5 of lead, and 3 of tin, and melts at 203° F.
Página 79 - The fourth and last law we have to consider is a very simple one, and will not require much illustration. It may be called the law of Compound Proportion, and teaches that the combining proportion of a compound body is the sum of the combining proportions of its components.
Página 223 - This reagent is easily prepared by transmitting a stream of sulphuretted hydrogen through a solution of...
Página 121 - ... combination with one substance, than it enters into union with some other, attacking the materials of which the apparatus used may be constructed. The...
Página 119 - A more convenient process, and one by which it is obtained in a pure state, is by the action of water on the periodide of phosphorus (567).
Página 286 - ... with twice its weight of water. It crystallizes in tables which are not deliquescent and contain no water of crystallization. It enters into fusion at 426° F., but at higher temperatures undergoes decomposition. It is frequently cast into small sticks and used by surgeons as a cautery. It is soluble in its own weight of cold and half its weight of iiot water, and, when in contact with organic matter, turns black in the rays of the sun.
Página 169 - Iodide of potassium 1 eq. -f- 1 eq 165.45 KI 604. Iodide of Potassium. — This compound is formed with evolution of heat and light, when potassium is heated in contact with iodine : it is the sole residue after decomposing iodate of potassa by heat; and by neutralizing potassa with hydriodic acid it is obtained in solution. The simplest process for preparing it in quantity is to add iodine to a hot solution of pure potassa until the alkali is neutralized, when iodide of potassium and iodate of potassa...
Página 4 - Bruno, preferring the philosophy of Pythagoras and of Plato, soon found himself in conflict with his teachers. Pythagoras had taught that the sun was the centre of our system, and that the earth was but a planet revolving round it, and Pythagorean student as he was, Giordano naturally followed the teaching of Copernicus on the same subject, despite all that Father Anselm could urge. And indeed Giordano had latterly shunned the kind old monk, being unwilling to give him needless pain...
Página 256 - A solution of mercuric chloride containing 13 '55 grms. to the litre, 1 cc =0'1 grm. Hg. The process is founded on the fact that, if a solution of mercuric chloride be added to one of potassic iodide, in the proportion of one of the former to four of the latter, mercuric iodide is formed, and immediately dissolved, until the balance is overstepped, when the red colour is developed ; the final reaction is very sharp, and with solutions properly made is very accurate. The mercuric solution must always...
Página 239 - ... from the mould with a piece of wood. Thus prepared, it must be preserved in close vessels containing pure water. When phosphorus is perfectly pure it is semitransparent, and has the consistence of wax : it is so soft that it may be cut with a knife.
