Uranyl nitrate
Uranyl nitrate (UO2(NO3)2) is a water soluble yellow uranium salt. The yellow-green crystals of dioxouranium nitrate hexahydrate are triboluminescent.
Uranyl nitrate can be prepared by reaction of uranium salts with nitric acid. It is soluble in water, ethanol, acetone, and ether, but not in benzene, toluene, or chloroform.
