It is colorless or white triclinic crystalline powder. It is soluble in water, the solubility is 1.75g/100ml water at 0℃, the solubility is 5.3g/100ml water at 20℃. It is insoluble in alcohol. Queous solution is acidic and unstable. It is stable in solid crystalline form; decomposes on heating, evolving oxygen; completely decomposes at about 100°C; moderately soluble at ordinary temperature, 5.29 g/100 mL at 20°C; decomposing slowly at room temperature and more rapidly when the solution is warmed; insoluble in alcohol.
