It is easy to volatilize and dissolve in water with any ratio. The mass fraction of 98% or more of HNO3 is called “Smoke---free nitric acid”. Because this kind of acid is easy to volatilize, it will form white smoke when mixed with humid air and it has causticity.

Chemical property:
(1) It has the quality of acid.
