A uranate is a ternary oxide involving the element uranium in one of the oxidation states 4, 5 or 6. A typical chemical formula is M x U y O z , where M represents a cation. The uranium atom in uranates(VI) has two short collinear U–O bonds and either four or six more next nearest oxygen atoms. [ 1 ]
Sodium uranate may be obtained in the amorphous form by heating together urano-uranic oxide and sodium chlorate; or by heating sodium uranyl acetate or carbonate. The crystalline form is produced by adding the green oxide in small quantities to fused sodium chloride, or by dissolving the amorphous form in fused sodium chloride, and allowing ...

Uranyl nitrate is important for nuclear reprocessing.It is the compound of uranium that results from dissolving the decladded spent nuclear fuel rods or yellowcake in nitric acid, for further separation and preparation of uranium hexafluoride for isotope separation for preparing of enriched uranium.
Chien Français Blanc et Noir, the original breed that evolved over centuries and was influenced in the 19th century by crosses between the Poitevin and the Grand Gascon Saintongeois. [1] Chien Français Blanc et Orange; Chien Français Tricolore, the classic hound that follows a hunter on horseback. It is similar in appearance to the Poitevin.
The compound can be prepared by treating uranium trioxide]] with acetic acid: . UO 3 + 2 CH 3 COOH + H 2 O → UO 2 (CH 3 COO) 2 ·2H 2 O. The acetate ligands of uranyl acetate can be replaced to give a variety of uranyl complexes. [6]
The Grand Anglo-Francais Tricolore is a breed of dog used in hunting as a scenthound, usually in packs. It is one of the Anglo-French hound breeds which were created by crossing French scenthounds with English (Anglo) Foxhounds .
The compositions were variable and depended upon the leachant and subsequent precipitating conditions. The compounds identified in yellowcakes include uranyl hydroxide, uranyl sulfate, sodium para-uranate, and uranyl peroxide, along with various uranium oxides. Modern yellowcake typically contains 70% to 90% triuranium octoxide (U 3 O 8) by weight.
