The equation 6HNO3 + 3Fe -> 3Fe(NO3)2 + 3H2O + 6NO

  1. Detailed information about the equation 6HNO3 + 3Fe -> 3Fe(NO3)2 + 3H2O + 6NO:

The above equation describes the reaction between nitric acid (HNO3) and iron (Fe). In this reaction, iron reacts with nitric acid to produce iron(II) nitrate (Fe(NO3)2), water (H2O), and nitric oxide gas (NO).

  1. Reaction conditions

This reaction occurs when iron comes into contact with concentrated and heated nitric acid.

  1. Reaction process

This process consists of two stages:

  • First, iron reacts with nitric acid to produce iron(II) nitrate and hydrogen gas.
  • Next, iron(II) nitrate reacts with more nitric acid to produce iron(III) nitrate, water, and nitric oxide gas.
  1. Phenomena occur

When the reaction occurs, you will see iron gradually dissolve in the acid solution and brown NO gas is released. Simultaneously, the formed solution of iron(II) nitrate has a light blue color.
