Sodium hydrogen sulphate: Does not have an individual approval but may be used under an appropriate group standard

Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]:

· Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.

Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]:

· TOXIC and/or CORROSIVE; inhalation, ingestion or skin contact with material may cause severe injury or death.

Corrosive to metals and tissues; Toxic by ingestion, inhalation, or skin contact; [CAMEO] Aqueous solutions are strong acids; [Merck Index] Harmful if swallowed; Do not inhale dust or aerosol; may cause acute lung edema if inhaled; [MSDSonline] Based on animal studies, not a skin irritant; [CHEMINFO]

Acidic salts, such as SODIUM BISULFATE, SOLUTION, 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. The combination of calcium hypochlorite, sodium hydrogen sulfate, starch, and sodium carbonate, when compressed, caused the materials to incandescence, followed by explosion, [Ind. Eng. Chem., 1937, 15, 282].
