Usage

Description

Sulphon Black RA is a red light black dye that exhibits moderate solubility in water, resulting in a violet black color. It is slightly soluble in ethanol, producing a purple shade. The dye's color changes when exposed to strong sulfuric acid, turning greenish-blue, and when diluted, it becomes a deep red. In an aqueous solution, the addition of strong hydrochloric acid results in a deep red precipitate, while the combination with strong sodium hydroxide solution yields a purplish-red color.
