Question

what will happen on heating Nitric acid ​

Answer 1

Nitric acid is prepared by reaction of nitrogen dioxide (NO2) with water. The nitric oxide (NO) by-product usually gets oxidized again by the oxygen in air to produce additional nitrogen dioxide starting material. ... Nitric acid can be decomposed by heat or light as shown below: 4 HNO3 → 2 H2O + 4 NO2 + O2.

Answer 2

HNO3 8-------D 2H2O+4NO2+O2
