Página xxx - Open dishes, which will bear heat without cracking, are necessary implements in the laboratory for conducting the evaporation of liquids. The best evaporating-dishes are those made of Berlin porcelain, glazed both inside and out, and provided with a little lip projecting beyond the rim. The dishes made of Meissen porcelain are not glazed on the outside, and are not so durable as those of Berlin manufacture ; but they are much cheaper, and with proper care last a long time. The small Berlin dishes...
Página 13 - Place a piece of charcoal — that of bark is best — in a deflagrating spoon. Kindle the charcoal by holding it in the flame of a lamp, and then introduce it into a bottle of oxygen. It will burn vividly, throwing off brilliant sparks if bark charcoal has been employed. In this experiment, as in the preceding, the products of the combustion are obviously gaseous, no solid substance being formed.

The gases combine with an explosion ; which is, however, much mitigated in violence by the elastic action of the above-mentioned air column. At the high temperature employed (132°), the water formed retains the gaseous condition. On removing the cork, and allowing the 54 VOLUME-RATIO OF HYDROGEN AND NITROGEN IN AMMONIA.

It is excessively irritating and suffocating, even when inhaled in exceedingly small quantities. Any attempt to breathe the undiluted gas would undoubtedly be fatal. Under a pressure of 4 atmospheres at 15° it is condensed to a yellow mobile liquid, having a sp. gr. of 1-33 ; this liquid has never yet been solidified....
Página 492 - Heat a small fragment of lead upon charcoal in the oxidizing flame of the blowpipe, and observe the gray film of suboxide which forms at first, and the yellow incrustation of litharge which is obtained subsequently. The litharge may be melted if a strong, hot flame be thrown upon it.

To fill the gasholder with water, close d, open the stopcocks a, b, and e, and pour water into the cistern B ; the water entering A will expel the air through...
Página 105 - It can not be well collected over water at the ordinary temperature, since it is rather easily soluble therein ; though the difficulty may be obviated in part by evolving the gas rapidly, or by passing the deliverytube to the top of the bottle in which the gas is collected. It must not be left standing over water, since it would soon be entirely absorbed. In experimenting with chlorine, care must always be taken not to inhale it. The reaction which occurs in this experiment may be thus formulated...
Página 33 - In the form of ice, and as it falls from the clouds as rain or snow, it is, indeed, tolerably free from foreign substances ; but after having once soaked into the ground, it becomes charged with a variety of mineral and other substances, which, being soluble in water, are dissolved by it as it trickles through the earth. Where the proportion of soluble matter contained in the water is unusually large, and particularly if it possesses marked medicinal properties, the water is called mineral water,...
