Yellow liquid, emitting red fumes on exposure
to moist air. d 1.84. bp 126-127°.
mp 77°. Dec in
presence of moisture into vanadic acid and HCl. When a small quantity
of water is added, it becomes thick and almost blood-red because of
formation of vanadic acid. Keep tightly closed. LD50 orally in rats: 0.14 g/kg (Smyth).
