How Can Nitric Acid be Synthesised in the Lab?

Industrially, nitric acid is synthesised by the reaction between nitrogen dioxide and water. However there are other ways this compound can be synthesised, but these are typically restricted to a lab as they’re not commercially viable.

Thermal Decomposition of Copper (II) Nitrate

This reaction produces nitrogen dioxide and oxygen, which are subsequently passed through water to generate nitric acid:

2 Cu(NO3)2 → 2 CuO (s) 4 NO2 (g) O2 (g)

The Reaction Between Nitrate Salt and Sulphuric Acid

Nitric acid can also be synthesised via a reaction between any nitrate salt (for example, sodium nitrate) and a strong solution of sulphuric acid (over 96%), followed by distillation at 83°C (nitric acid boiling point). All non-volatile matter (mostly metal sulphate) remains in the distillation container:

2 NaNO3 H2SO4 → 2 HNO3 Na2SO4

Obtaining Pure Solutions

Typically solutions go up to 68% acid, which is the maximum possible azeotrope with 32% water. However, for specialised applications, it’s possible to increase the concentration via distillation using magnesium nitrate or sulphuric acid as dehydrating agents.

It’s important to conduct this procedure in all-glass equipment and at low pressure to limit decomposition of nitric acid.
