Usage

Description

AZO BLUE is a synthetic dye characterized by its red light purple color. It is soluble in water, turning the solution purple, and when exposed to strong sulfuric acid, it turns blue and forms a purple precipitate upon dilution. The dye solution exhibits purple precipitation when mixed with hydrochloric acid, and it produces a red product when combined with a sodium hydroxide solution.
