It is a purple red crystal of monoclinic system. It's easy in moisture absorption. Melting point:60℃. It will be decompose at 125.5℃. The chromium nitrate nonahydrate can be easily dissolved in water, alcohols and acetone, acids. Its aqueous solution is green when heated, turn into reddish-purple rapidly after cooling. It has a property of rot, and it can burn our skin. It will burn once in contact with easy combustion things.
