Stran 148 - A more accurate method is based on the fact that a body immersed in water loses in weight an amount equal to the weight of the water displaced. The substance has the weight A in air, say. Suspended by a fine thread in a vessel of water, it has the weight W.
Stran 148 - A superscript epsilon (e) indicates an editorial change since the last revision or reapproval. INTRODUCTION The specific gravity is the weight of any given volume of a substance divided by the weight of an equal volume of water. As both the weight and volume of wood vary with the amount of moisture contained in the wood, specific gravity as applied to wood is an indefinite quantity unless the conditions under which it is determined are clearly specified. The specific gravity of wood is generally...
Stran 46 - ... 2. In oxidizing flame the borax bead is amber colored; in reducing flame, bottle green. 3. Ammonia precipitates brownish-red iron hydroxide. A few drops of nitric acid should always be added to the solution to insure oxidation of the iron. 4. To detect state of iron, a borax bead made blue with malachite is changed to opaque red by a ferrous compound, and to green by a ferric compound. (Use a neutral flame.) LEAD, Pb. 1. On charcoal with soda in reducing flame a malleable button of lead and a...
Stran 10 - A compound in which only part of the hydrogen of the acid has been replaced by a metal is called an acid salt.
Stran 45 - Borax and sodium metaphosphate beads are blue in oxidizing flame and opaque red in reducing flame. In the presence of iron, the oxidizing flame bead is green or bluish-green. 3. On charcoal with soda in reducing flame and also with salt of phosphorous and metallic tin or charcoal, metallic copper (malleable) is obtained. 4. Solutions of copper minerals are blue (green in the presence of iron). Ammonia produces a deep blue coloration. 5. Copper solutions touched to a bright surface of iron, such as...
Stran 153 - ... scratched by another, or by the finger nail, or by the knife or file. To give precision to this physical character a scale of hardness is employed, as follows, those minerals which occur rather abundantly in certain rocks being printed in italics : — 1. Talc 2. Gypsum 3. Calcite 4. Fluorite 5. Apatite 6. Orthoclase 7. Quartz 8. Topaz 9. Corundum 10. Diamond The finger nail has a hardness of about 2.5, and the knife blade about 5.5 to 6.2, window glass has a hardness of about 5.5. Crystalline...
Stran 64 - Hence the law of constancy of interfacial angles, "in all crystals of the same substance, the angles between corresponding faces are...
Stran 50 - Nitric acid solutions of silver minerals on the addition of hydrochloric acid give a white curdy precipitate which changes to violet on exposure to light and is soluble in ammonia.
Stran 41 - ... an orange coating stippled with peach-red. 3. In the open tube antimony minerals give a non-volatile, amorphous, white sublimate on the under side of the tube. 4. Concentrated nitric acid oxides antimony sulphids and sulphosalts to antimony oxide, a white precipitate soluble in potassium hydroxide. ARSENIC, As. A. — Compounds Without Oxygen 1. On charcoal most arsenic minerals give a white volatile coating far from the assay and fumes with characteristic odor of arsine. 2. In the open tube...
