Short-term toxicity to aquatic invertebrates
Administrative data
- Endpoint:
- short-term toxicity to aquatic invertebrates
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods
- Justification for type of information:
- Sulfuryl dichloride hydrolyzes slowly in moist air and reacts violently with water, forming hydrochloric acid and sulfuric acid.
2 H2O + SO2Cl2 → 2 HCl + H2SO4
Hydrogen chloride is a colourless gas which has a pungent odor, and has a vapour pressure of 42,200 hPa at 20°C and a water solubility of 823 g/L at 0°C. Its aqueous solution (called hydrochloric acid) possesses strong acidity. Hydrogen chloride is readily dissociated in water into hydrated protons and chloride ion. Sulfuric acid is a strong mineral acid that dissociates readily in water to sulfate ions and hydrated protons, and is totally miscible with water.
