In industries nitric acid is prepared by Ostwald process.
NH3 + O2 ------> NO + H2O
Catalyst is Platinum at 800C temperature.
NO + O2 ------> NO2
NO2 + H2O + O2 -------> HNO3
Balance them yourself....very easy...
And it is prepared in laboratory by heating nitre or Chile saltpetre with conc. sulphuric acid at a temperature less than 200C
KNO3 + H2SO4 -------> KHSO4 + HNO3
NaNO3 + H2SO4 -------> NaHSO4 + HNO3.
