Nitric acid can be prepared by using nitrate salts of sodium or potassium with a non volatile acid.
Reactants :-Sodium nitrate or potassium nitrate and Sulphuric acid.
Product :-Sodium bisulphate and Nitric acid.
Provided the temperature is less than 200 degree Celsius.

Answer:- Nitric acid is obtained in laboratory by distilling conc.H2SO4 with potassium nitrate (KNO3) or sodium nitrate (NaNO3).
Hence the reactants include conc.H2SO4 with KNO3 or NaNO3.
As sulphuric acid is non-volatile in nature, so on reacting with volatile compounds we get simply volatile nitric acid.
Reactions:- KNO3+H2SO4(conc.) at 200°c gives KHSO4+HNO3.
NaNO3+H2SO4(conc.) at 200°c gives NaHSO4+HNO3.
Hope its helps you mate.......
