Question

In the laboratory preparation of nitric acid, what is the name of reactants?

• A. Conc sulphuric acid
• B. Nitre or chile salt petre
• C. Conc hydrochloric acid
• D. Both A and B

Answer 1

The correct option is D Both A and B

Laboratory synthesis is done by reaction of approximately equal masses of any nitrate salt such as sodium nitrate with 96% sulphuric acid (H₂SO₄), and distilling this mixture at nitric acid's boiling point of 83 °C. A nonvolatile residue of the metal sulfate remains in the distillation vessel. The red fuming nitric acid obtained may be converted to the white nitric acid.$NaN{O}_3+H_{2}S{O}_4\to 2HN{O}_3+N{a}_{2}S{O}_4$
