In simple substances like potassium chloride it seems evident that one kind of dissociation only is possible.
These colour changes are connected with a dissociation of the molecules.
They are yellowish-red solids, which behave as weak bases, their salts undergoing hydrolytic dissociation in aqueous solution.
The history of its dissociation is connected with that of the class, viz.
The result of this treatment is that the comparatively heavy oils undergo dissociation, as shown by the experiments of Thorpe and Young, into specifically lighter hydrocarbons of lower boiling points, and the yield of kerosene from ordinary crude petroleum may thus be greatly increased.
