Chromium(III) nitrate is the chromium salt of nitric acid. This nitrate exists as a nona hydrate Cr(NO3)3.9H2O. The anhydrous salt forms green crystals and very soluble in water. At 100 °C it decomposes. The hydrate has a red-violet color. Its melting point is 36–37 °C. Chromium nitrate is used in the production of alkali metal-free catalysts and in pickling.
