| Hazard Information | Back Directory | [Chemical Properties]
Violet, crystalline powder. contains 47.5% silver; decom-
posed by alcohol; light-sensitive, use dark-colored
bottles.
| [Uses]
In gas masks. | [Hazard]
Dangerous explosion risk, may detonate if
shocked or heated.
| [Purification Methods]
The salt forms violet crystals which can be crystallised from hot H2O (soluble is 9g/L at 20o). Store it in the dark. This oxidising agent is decomposed by light. [Lux in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 1463 1963.] |
