【Specification of Acid Black 10B】
Acid Black 1 is soluble in water, resulting in a blue-black aqueous solution. Adding concentrated hydrochloric acid causes green light and blue precipitation to form. It generates blue precipitation upon addition of sodium hydroxide solution. In ethanol, it dissolves to appear blue, while its solubility in acetone is slight.
