Thus..sulphate of lead contains (1) lead, (2) sulphur, (3) oxygen; the sulphantimonite, jamesonite, contains (1) lead and iron, (2) antimony, (3) sulphur..The replacing power of the elements is in proportion to their combining power, the combining power being reckoned in number of atoms of oxygen (or sulphur, or the acidific element, whatever it may be). |
