Yellow powder. Red light yellow to orange. Soluble in water, ethanol , ethyl, benzene and ethylene glycol, slightly soluble in acetone. In purple sulfuric acid, and it will produce red after diluted precipitation. In a blue nitric acid, then turned into orange. Its water solution with hydrochloric acid was red, and the precipitation produce; Add sodium hydroxide solution unchanged, excessive yellow produced after precipitation. Copper ions in dyeing color green dark; Iron ions in a shallow color; Chrome ions in a slightly change. Discharge the gender is good.

Appearance is yellow powder. Soluble in water, soluble in alcohol, ether, benzene and ethylene glycol ether, slightly soluble in acetone. It is purple in concentrated sulfuric acid solution, red precipitate after dilution; in case of nitric acid is blue, then change It is orange. The hydrochloric acid is red in the aqueous solution and precipitates; the sodium hydroxide solution is added, and a yellow precipitate is formed after the excess. The copper ion is dark and dark when dyed; the iron ion is lighter; the chromium is encountered. The ions are slightly changed. The discharge is good.
