    Molecular formula:Na2Cr2O7H2O

    Molecular weight:298.00

    Properties: Orange red crystal which will dehydrate to generate copper brown anhydride at 84.6 centigrade degree. It dissolves in water, but not in alcohol. Characterized by a strong moisture absorption and a good hygroscopy, it is a powerful oxidant. While coming into contact with an organic substance, it will burn, therefore, it should be sealed for storage. This product is toxic.
