Content
Getting
- Upon slow (months) evaporation of a solution of the plutonium (IV) compound in nitric acid, color crystals from dark green to black green Pu (NO 3 ) 4 • 5H 2 O.
Physical Properties
Plutonium (IV) nitrate forms a crystalline hydrate of the composition Pu (NO 3 ) 4 • 5H 2 O — dark green crystals of rhombic syngony , space group F dd2 , cell parameters a = 1.114 nm, b = 2.258 nm, c = 1.051 nm, Z = eight.
The crystalline hydrate melts in its own crystallization water at 95-100 ° C.
It is well soluble in nitric acid (dark green solution) and water (brown solution). It is soluble in acetone , ether .
Chemical Properties
- When heated to 150-180 ° C, it decomposes with autooxidation to plutonium (VI) with the formation of plutonyl nitrate PuO 2 (NO 3 ) 2 .
- Upon evaporation of concentrated nitric acid solutions of plutonium nitrate and alkali metal nitrates, double nitrates of the composition Me 2 [Pu (NO 3 ) 6 ] are formed, where Me = Cs + , Rb + , K + , Tl + , NH 4 + .
Toxicity
Plutonium nitrate is both radioactive and extremely toxic due to its high solubility in water.
