Usage

Description

Acid red 163 is a synthetic dye characterized by its red color. It is soluble in water, producing a red hue, and slightly soluble in alcohol, also resulting in a red color. When it comes into contact with strong sulfuric acid, the color shifts to purple, and upon dilution, it turns pink. In an aqueous solution, the addition of strong hydrochloric acid results in a red color, while the introduction of a concentrated sodium hydroxide solution leads to a red-orange-brown color.

Uses
