Seite 14 - English name) ; or when the names of two or more elements begin with the same letter, two letters are used as the symbol, one of which is always the first letter of the name of the element.
Seite 9 - When an acid contains oxygen, its name is generally formed by adding the terminal ic either to the name of the element with which the oxygen is united, or to an abbreviation of that name; thus sulphur forms, with oxygen, sulphuric acid; nitrogen, nitric acid; and phosphorus, phosphoric acid. But it frequently happens that the same element forms two acids with oxygen ; and when this occurs, the acid containing the...
Seite 12 - If we take a salt* to be the product of the mutual action of an acid and a metal or base upon each other, normal salts are obtained by exchanging the whole of the replaceable hydrogen of the acid for an equivalent amount of a metal, or of a positive compound radical, such at ammonium, NHt.
Seite 9 - A more intelligible definition to ordinary readers is that which is adopted by Frankland, in which an acid is described "as a compound containing one or more atoms of hydrogen, which become displaced by a metal, when the latter is presented to the compound in the form of a hydrate.

Seite 35 - The weight of 1 litre of hydrogen being called 1 crith, the volume-weight of other gases, referred to hydrogen as a standard, may be expressed in terms of this unit. For example, the relative volume-weight of chlorine being 35'5, that of oxygen 16, that of nitrogen 14, the actual weights of 1 litre of each of these elementary gases, at 0°C.
Seite 3 - Hence the law : — Equal volumes of all gases and vapours contain at the same temperature and pressure an equal number of molecules...
Seite 34 - The crith is the weight of one litre or cubic decimetre of hydrogen at 0° C. and at a pressure of 760 millimetres of mercury. The following is Dr. Hofmann's description of the value and applications of this unit. " The actual weight of this cube of hydrogen, at the standard temperature and pressure mentioned, is...
Seite 5 - The chemical name of a substance should not only identify and individualize that substance, but it should also express the composition and constitution of the body, if a compound, to which it is applied. The first of these conditions is readily attained; but the second is much more difficult to secure, inasmuch as our ideas of the constitution of chemical compounds — of the mode in which they are built up as it were — require frequent modification.
