If forms two series of salts, one, the uranous compounds, are derived from the oxide U02, the other, the uranyl compounds, contain the divalent group U02.
In the us uranous sulfate was number of wrong turns.
It fires when heated in air, and dissolves in acids to form uranous salts.
Metallic uranium, as shown by Peligot, can be obtained by the reduction of a mixture of dry chloride of potassium and dry uranous chloride, UC1 4, with sodium at a red heat.
The area years uranous salt is approach is to.
The filtrate contains the uranium as uranous and the iron as ferrous salt.
Uranous bromide, UBr4, and uranous iodide, U14, also exist.
Uranous chloride, UC14, was first prepared by Peligot by heating an intimate mixture of the green oxide and charcoal to redness in a current of dry chlorine; it is obtained as sublimate of black-green metallic-looking octahedra.
Uranous Compounds.-Uranium dioxide, UO 2 (Berzelius's metal), is a brown to copper-coloured powder, obtained by heating U308 or uranyl oxalate in hydrogen.
Uranous hydrate is obtained as reddish-brown flakes by precipitating a uranous solution with alkali.
With hydroflouric acid it yields uranous fluoride, UF 4, which forms double salts of the type MF UF 4.
