- SbCl3
- IUPAC Name:
- antimony(3+) trichloride
- Details on test material:
- Chemical name: Antimony trichloride
CAS-Number: 10025-91-9
Molecular formula: SbCl3

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.
