Bauxite is a hydratedoxide of aluminium of the ideal composition, Al2O3.2H2O.
3
The chief natural compounds of aluminium are four in number: oxide, hydroxide ( hydratedoxide), silicate and fluoride.
4
For gas engines, etc., it is, however, better to pass the gas through some hydratedoxide of iron to remove the sulphureted hydrogen.
5
White lead, by which we must be understood to mean the carbonate, always contains when commercially prepared a certain proportion of hydratedoxide.
6
In producing this result two agencies are at work, there is the action of electrolysis and the formation of a hydratedoxide of iron.
7
A purple powder is capable of being produced from bismuth by passing chlorine gas through the hydratedoxide suspended in a saturated solution of potash.
