Salts, Acidic Inorganic/Organic

None of these materials are highly flammable. Inorganic salts are generally noncombustible as well. Salts containing organic groups are in principle combustible, although they may burn with difficulty.

Materials in this group are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pHs of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

Widely variable. Solutions of these materials are generally corrosive to skin and irritating to mucous membranes.

Ferric chloride, aluminum sulfate, ammonium bromide, antimony tribromide, cupric oxalate, ferric sulfate.
