Green odorless aqueous solution. Sinks in and mixes with water.
Acidic inorganic salts, such as NICKEL TETRAFLUOROBORATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's 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.
Ingestion causes irritation of mouth and stomach. Liquid irritates eyes and skin and may cause dermatitis.
ConfKmed carcinogen.
Moderately toxic by ingestion and
inhalation. When heated to decomposition it
emits very toxic fumes of F-. See also

COMPOUNDS.
