They are of a reddish colour and usually crystallize well; on heating with concentrated acids are usually transformed into the purpureo-salts.
It is monobasic and yields salts which only crystallize with great difficulty; when liberated, from these salts by a mineral acid it forms a syrupy nonvolatile mass.
The salts of all the metals of this group usually crystallize well, the chlorides and nitrates dissolve readily in water, whilst the carbonates, phosphates and sulphates are either very sparingly soluble or are insoluble in water.
Hence arise various mistaken beliefs, such as the belief in revelation which not only injures the moral As feudalism passed from its age of supremacy into its age of decline, its customs tended to crystallize into fixed forms.
Tafia rum and a waxy, sticky sugar syrup subsequently became important products; but not until the end of the century were the means found to crystallize sugar and so give real prosperity to the industry.
These crystallites (q.v.) show that the glassy rock has a tendency to crystallize which is inhibited only by the very viscous state of the glass and the rapidity with which it was cooled.
They all crystallize in the monoclinic system, often, however, in forms closely resembling those of the rhombohedral or orthorhombic systems. Crystals have usually the form of hexagonal or rhomb-shaped scales, plates or prisms, with plane FIG.
They are soluble in water, have an astringent, acid, and sweetish,, .taste, react acid to litmus, and crystallize in regular octahedra.
Bergman also observed that the addition of potash or ammonia made the solution of alumina in sulphuric acid crystallize, but that the same effect was not produced by the addition of soda or of lime (De confectione aluminus, Bergman's Opusc. i.
This salt is also formed by dissolving tin in strong hydrochloric acid and allowing it to crystallize, and is industrially prepared by passing sufficiently hydrated hydrochloric acid gas over granulated tin contained in stoneware bottles and evaporating the concentrated solution produced in tin basins over granulated tin.
Appears to be owing chiefly to the fact that, while the latter crystallize in the regular system, metals of Class I.
The coefficient of expansion is constant for such metals only as crystallize in the regular system; the others expand differently in the directions of the different axes.
They crystallize in plates, and for the most part distil without decomposition.
If so, these are likely one day to crystallize into full dogmas; and, even while not yet " declared," they have the same claim upon faith.
Sodium combines directly with the halogens to form salts which are soluble in water and crystallize in the cubic system.
The bromide and iodide crystallize from hot solutions in anhydrous cubes; from solutions at ordinary temperatures in monoclinic prisms with 2H 2 O; and at low temperatures with 5H 2 O.
The kelp obtained by any of these methods is then lixiviated with water, which extracts the soluble salts, and the liquid is concentrated, when the less soluble salts, which are chiefly alkaline chlorides, sulphates and carbonates, crystallize out and are removed.
They usually crystallize well and are readily reduced.
The formulary of the papal bulls began to crystallize, and the letters amassed in the papal offices were differentiated clearly into great and little bulls, according to their style, arrangement and signs of validation.
First a small quantity of one of the pure components begins to crystallize out, and the rate of cooling is thereby diminished owing to the latent heat liberated by the change of state.
It was found that substances like mineral salts, which crystallize well from solution, passed such membranes with comparative ease, while the jelly-like substances such as albumen passed with extreme slowness if at all.
The salts of nitric acid, known as nitrates, are mostly readily soluble in water and crystallize well.
The free pararosaniline, C19H19N30, and rosaniline, C20H21N30, may be obtained by precipitating solutions of their salts with a caustic alkali, colourless precipitates being obtained, which crystallize from hot water in the form of needles or plates.
It is, at any rate, established that carbon can crystallize as diamond from solution in iron, and other metals; and it seems that high temperature and pressure and the absence of oxidizing agents are necessary conditions.
The felspathoid minerals, sodalite, haiiyne and nosean, which crystallize in isometric dodecahedra, are very frequent components of the phonolites; their crystals are often corroded or partly dissolved and their outlines may then be very irregular.
Berzelius as to their composition; and his observation that corresponding phosphates and arsenates crystallize in the same form was the germ from which grew the theory of isomorphism which he communicated to the Berlin Academy in December 1819.
The heptahydrate is obtained by dissolving the metal or its oxide, hydroxide or carbonate in dilute sulphuric acid (preferably in the presence of a small quantity of nitric acid), and allowing the solution to crystallize between 15° and 20° C. It crystallizes in emerald-green rhombic prisms and is moderately soluble in water.
Rydberg (q.v.) (1828-1895) closely followed Bostrom, and in his numerous and varied writings did much to crystallize and extend the principles of idealism.
Beginning with the province of Aconcagua the coast elevations crystallize into a range of mountains, the Cordillera Maritima, which follows the shore line south to the province of Llanquihue, and is continued still farther south by the mountain range of Chiloe and the islands of the western coast, which are the peaks of a submerged mountain chain.
These salts crystallize out when the water is partially evaporated and may be used with hot water at home, the best imitation of the Carlsbad water being obtained by mixing with hot water the powdered Carlsbad salts (pulverformig), which contain all the constituents of the natural water.
Boiling alcohol extracts from the root a neutral substance in the form of crystalline prisms, which crystallize in scales from boiling water.
