  Properties and features: Chromium nitrates exist anhydrous variety and couples of hydrates. The anhydrous chromium nitrate is a little green powder while the common nonahydrate is a purple crystal of monoclinic system. It will be dissolved in crystal water itself at temperature of 66.3°C or boil and decompose at 125.5°C. The hydrate chromium nitrate is likely to lose some crystal water due to weathering in the air. In turn, it is subject to deliquescence. The nonahydrate chromium nitrate can be easily dissolved in water, acids, alkalis, alcohols and acetone.
