| Chemical Properties | Dark blue powder. Solubility in water (20 ℃) for 80g / L, (50 ℃) for 90g / L. Strong sulfuric acid is reddish brown, diluted into blue; in nitric acid is orange, diluted no change. Aqueous solution is blue, add 1mol/L sodium hydroxide is still blue, then add insurance powder and warm to dark red, then add sodium perborate to red, no change after dilution. Chemical properties are more active, poor stability, alkaline hydrolysis resistance, not acid hydrolysis resistance. | |||||||||||||||||||||
