Materials and methods

Principles of method if other than guideline:
During dissolution testing the stability of antimony trichloride was tested in air-free ultrapure water. A defined amount of test substance was weighed in a flask and filles with water. The reaction is minitred visually.
GLP compliance:
no
Type of method:
other: dissolution testing

Test material

Reference
Name:
Unnamed
Type:
Constituent
Details on test material:
Chemical name: Antimony trichloride
CAS-Number: 10025-91-9
Molecular formula: SbCl3
Molecular weight: 228.11 g/mol
Appearance: white to yellow crystalline pieces
Storage: store away from incompatible substances in a dry, well ventilated area

Results and discussion

Details on results:
A voluminous and white precipitate was observed for batch 1 after giving antimony trichloride into ultrapure water . No generation of heat was discoverable. For batch 2 a part of the compound remained undissolved. The aqueous solutions of antimony trichloride were acescent as shown by the listed pH-values.
