Coeff.: Not available. <br /> lonicity (in Water): Not available. <br /> Dispersion Properties: See solubility in water, diethyl ether. <br /> Solubility: Soluble in cold water, hot water, diethyl ether. <br /> Section 10: Stability and Reactivity Data <br /> Stability: The product is stable. <br /> Instability Temperature: Not available. <br /> Conditions of Instability: Incompatible materials, water <br /> Incompatibility with various substances: <br /> Highly reactive with metals. Reactive with oxidizing agents, organic materials, alkalis, water. <br /> Corrosivity: <br /> Extremely corrosive in presence of aluminum, of copper, of stainless steel(304), of stainless steel(316). Non-corrosive in <br /> presence of glass. <br /> Special Remarks on Reactivity: <br /> Reacts with water especially when water is added to the product. Absorption of gaseous hydrogen chloride on mercuric <br /> sulfate becomes violent @ 125 deg. C. Sodium reacts very violently with gaseous hydrogen chloride. Calcium phosphide <br /> and hydrochloric acid undergo very energetic reaction. It reacts with oxidizers releasing chlorine gas. Incompatible with, <br /> alkali metals, carbides, borides, metal oxides, vinyl acetate, acetylides, sulphides, phosphides, cyanides, carbonates. Reacts <br /> with most metals to produce flammable Hydrogen gas. Reacts violently(moderate reaction with heat of evolution)with <br /> water especially when water is added to the product. Isolate hydrogen chloride from heat, direct sunlight, alkalies (reacts <br /> vigorously), organic materials, and oxidizers (especially nitric acid and chlorates), amines, metals, copper and alloys (e.g. <br /> brass), hydroxides, zinc (galvanized materials), lithium silicide (incandescence), sulfuric acid(increase in temperature and <br /> pressure) Hydrogen chloride gas is emitted when this product is in contact with sulfuric acid. Adsorption of Hydrochloric Acid <br /> onto silicon dioxide results in exothmeric reaction. Hydrogen chloride causes aldehydes and epoxides to violently polymerize. <br /> Hydrogen chloride or Hydrochloric Acid in contact with the folloiwng can cause explosion or ignition on contact or <br /> Special Remarks on Corrosivity: <br /> p. 4 <br />
