Aqueous solution corrodes metals. 

ARSENIC (7440-38-2) Finely divided material forms explosive mixture with air. Decomposes on contact with acids or acid fumes, emitting fumes of arsenic. Contact of dust or powder with strong oxidizers can cause ignition or explosion. Violent reaction with bromine azide, bromine pentafluoride, bromine trifluoride, dichlorine oxide, hypochlorous acid, nitrogen trichloride, tribromamine hexaammoniate, nitrogen oxyfluoride, potassium chlorate, potassium dioxide, powdered rubidium, silver fluoride.

BROM (German) (7726-95-6) A powerful oxidizer. Violent reaction with reducing agents. Can cause fire and explosions in contact with organic or other readily oxidizable materials. Contact with water or steam forms hydrobromic acid and oxygen. Contact with aqueous ammonia, acetaldehyde, acetylene, acrylonitrile, hydrogen may cause violent reactions. Anhydrous material reacts violently with aluminum, titanium, mercury, or potassium wet material reacts with other metals. Incompatible with many materials, including alcohols. 

MERCURY (7439-97-6) Violent reaction with alkali metals, aluminum, acetylenic compounds, azides, boron phosphodiiodide (vapor explodes), bromine, 3-bromopropyne, chlorine, chlorine dioxide, ethylene oxide, lithium, metals, methyl silane (when shaken in air), nitromethane, peroxyformic acid, potassium, propargyl bromide, rubidium, sodium, sodium carbide. Forms sensitive explosive products with acetylene, ammonia (anhydrous), chlorine, picric acid. Increases the explosive sensitivity of methyl azide. Mixtures with hot sulfuric acid can be explosive. Incompatible with calcium, sodium acetylide, nitric acid. Reacts with copper, silver, and many other metals (except iron), forming amalgams. 

NITRIC ACID, MERCURY(II) SALT (10045-94-0) A powerful oxidizer. Violent reaction with reducing agents, combustibles, phosphinic acid, hypophosphoric acid, petroleum hydrocarbons. Forms heat- and/or shock-sensitive compounds with acetylene (forms mercury acetylide), ethanol (forms mercury fulminate), ferrocene, isobutene, phosphine, potassium cyanide, sulfur. Incompatible with strong acids, acetic anhydride, ammonia, ammonium hexacyanoferrate(II), organic azides, citric acid, hydrazinium perchlorate. 

Reactivity and Incompatibility Acetylene forms highly unstable acetyUdes with many metals, including copper, brass, mercury, potassium, silver, and gold. The dry acetylides are sensitive, powerful explosives. Acetylene may react violently with fluorine and other halogens (chlorine, bromine, iodine) and forms explosive compounds on contact with nitric acid. 

Reactivity and Incompatibility Mercury is a fairly unreactive metal that is highly resistant to corrosion. It can dissolve a number of metals, such as silver, gold, and tin, forming amalgams. Mercury can react violently with acetylene and ammonia.
