Xylenol Orange, Water Soluble, Reagent, ACS is a reagent used in organic chemistry. It is used as a tetrasodium salt as an indicator for metal titrations. When it is used for metal titrations it will appear red in the titrand and then it will turn yellow once it reaches its endpoint. The Reagent grade denotes that this chemical is the highest quality commercially available and that the American Chemical Society has not officially set any specifications for this material. Spectrum Chemical manufactured Reagent grade products meet the toughest regulatory standards for quality and purity.
