dilute/concentrated nitric acid 係咪 volatile?

Nitric acid "IS" definitely volatile !!!!!!!!!!!!!!!!!!!!!!
Because nitric acid boils at 83 oC ( a low boiling point)

chlorhydric acid (HCl) is also volatile .
It boils at -85 oC

sulphuric acid is NOT volatile .
Because it boils at 338 oC ( a quite high boiling point)

點解出左怪字-.-我想講係Nitric acid IS definitely volatile !!!!!!!!!!!!!!!!!!!!!!

Volatile acid應該係一d響room condition ge時候果一隻acid係in gas state...
所以nitric acid應該唔係
HCl同埋HBr呢d就會係volatile acid
