Question

give explanation 1. sulphuric acid has low volatility 2. oxoanions of a metal show higher oxidation State

Answer 1

a).Sulphuric acid shows low volatility when reacts with metal salts specially halides or nitrates because it can replace the metals from its salt.
For ex: 2NaCl + H2SO4 --> Na2SO4 + 2HCl
b)In oxoanions, metals form bonds with oxygen that is highly electronegative and hence they exhibit their highest oxidation states.

Hope would be a bit helpful..
