3 NO2 H2O → 2 HNO3 NO
The nitric oxide (NO) can be re-oxidised in the air to generate additional nitrogen dioxide which can then be used to synthesise nitric acid. From this process, solutions obtained are typically between 52 and 68% nitric acid.4 NH3 (g) 5 O2 (g) → 4 NO (g) 6 H2O (g)
In a second step, nitric oxide (NO) is oxidised in air to produce nitrogen dioxide (NO2, reaction 1), and subsequently absorbed in water to finally synthesise nitric acid (reaction 2). The by-product nitric oxide (NO) can be recycled for re-oxidation.Reaction 1: 2 NO (g) O2 (g) → 2 NO2 (g)
Reaction 2: 3 NO2 (g) H2O (l) → 2 HNO3 (aq) NO (g)
As an alternative, the final step can be done in the presence of oxygen:
4 NO2 (g) O2 (g) 2 H2O (l) → 4 HNO3 (aq)

Why is delivery so expensive?
As many of the chemicals we supply are hazardous, we are legally obligated to use ADR licensed couriers who are specialists in carrying such goods. Because these couriers are specialists they do cost more than most regular delivery services but you can rest assured that your order will reach you safely and legally.

Can I have a timed delivery slot?
We can offer an AM delivery service for some regions of the UK, please contact us for information before placing your order.
Nitric acid is a highly corrosive, inorganic mineral acid with the chemical formula HNO3. It’s typically sold at a concentration of 68% by volume, although stronger varieties are available. While nitric acid has a range of commercial and industrial applications,
When nitric acid reacts with ammonia, it produces a white crystalline salt called ammonium nitrate (NH4NO3). As a solid, ammonium nitrate is hygroscopic, which means it attracts moisture. Although the substance dissolves easily in water, it does not form hydrates.
Nitric acid has a wide range of industrial applications, although it’s primarily used in the manufacture of fertilisers as a precursor to ammonium nitrate. In fact, fertiliser production accounts for around 80% of the total global use of nitric acid.
