AMMMONIUM BISULFITE

ICSC: 1254

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
COLOURLESS TO YELLOW CRYSTALS.

CHEMICAL DANGERS:
The substance decomposes on heating or on contact with acids producing toxic fumes including sulfur oxides, nitrogen oxides and ammonia. Reacts violently with oxidants. Attacks many metals in presence of water at high concentration.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered.

PHYSICAL PROPERTIES

Decomposes below boiling point at 150°C
Relative density (water = 1): 2.0
Solubility in water, g/100 ml at 10°C: 267

ENVIRONMENTAL DATA

NOTES

Mainly sold as aqueous solution. Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
