Seite 86 - ... then add mercuric chloride solution until a permanent precipitate again forms ; allow to stand till settled, and decant off the clear solution for use; keep it in glass-stoppered blue bottles, and set away in a dark place to keep it from decomposing.
Seite 18 - In defining the unit of heat it is necessary to specify the temperature of the water because the amount of heat necessary to raise the temperature of one pound of water through one degree varies slightly at different temperatures.
Seite 73 - Ib. per square inch, is as low as is necessary. The concentration of the acid is effected in a lead-lined vessel, in which is a coil of lead piping heated by steam, the pressure in the vessel being kept down by means of an ordinary air-pump. No acid pump is needed, as the transfer from one vessel to another is effected by the pressure of the atmosphere. The comparatively cool weak...
Seite 84 - Quickly wipe off the moisture that has accumulated on the pipe, replace the bottle and open valve gently, filling the bottle about half full. This last operation should not occupy more than one minute. Remove the bottle at once, and insert in its neck a stopper with a vent hole for the escape of the gas.
