Uranyl acetate is the acetate salt of uranium oxide, a toxic yellow-green powder useful in certain laboratory tests. Structurally, it is a coordination polymer with formula UO 2 (CH 3 CO 2 ) 2 (H 2 O)·H 2 O.
Uranyl zinc acetate (ZnUO 2 (CH 3 COO) 4) is a compound of uranium.. Uranyl zinc acetate is used as a laboratory reagent in the determination of sodium concentrations of solutions using a method of quantitatively precipitating sodium with uranyl zinc acetate and gravimetrically determining the sodium as uranyl zinc sodium acetate, (UO 2) 3 ZnNa(CH 3 CO 2) 9 ·6H 2 O.
The uranyl ion is an oxycation of uranium in the oxidation state +6, with the chemical formula UO 2+ 2 . It has a linear structure with short U–O bonds, indicative of the presence of multiple bonds between uranium and oxygen.
2 ion represents the uranium(VI) state and is known to form compounds such as uranyl carbonate, uranyl chloride and uranyl sulfate. UO 2+ 2 also forms complexes with various organic chelating agents, the most commonly encountered of which is uranyl acetate. [4]
Neodymium(III) acetate is an inorganic salt composed of a neodymium atom trication and three acetate groups as anions where neodymium exhibits the +3 oxidation state. [2] It has a chemical formula of Nd(CH 3 COO) 3 although it can be informally referred to as NdAc because Ac is an informal symbol for acetate. [8] It commonly occurs as a light ...

Some suitable negative stains include ammonium molybdate, uranyl acetate, uranyl formate, phosphotungstic acid, osmium tetroxide, osmium ferricyanide [clarification needed] [2] and auroglucothionate. These have been chosen because they scatter electrons strongly and also adsorb to biological matter well.
Another method is the thermal decomposition of a complex, such as an acetate complex. For example, microcrystalline barium diuranate, BaU 2 O 7, was made by thermal decomposition of barium uranyl acetate at 900 °C. [4] Ba[UO 2 (ac) 3] 2 → BaU 2 O 7... (ac=CH 3 CO 2 −) Uranates can be prepared by adding alkali to an aqueous solution of a ...
