Other InformationHide

This section is currently hidden. Click the show button to view.
Thermal Behaviour:
Sublimates when heated in a closed tube, condensing in the upper (cooler) part of the tube in minute octahedrons.
Notes:
Slightly soluble in hot water.
Health Risks:
A highly toxic substance. Contains arsenic in a highly soluble form.

Avoid handling unless absolutely necessary. Wear protective gloves and wash them thoroughly after handling.

Avoid inhaling dust when handling.

Never lick or ingest.
