The equation 4HNO3 + Fe(OH)3 -> 2NO2 + 2H2O + Fe(NO3)3

  1. Detailed information about the equation 4HNO3 + Fe(OH)3 -> 2NO2 + 2H2O + Fe(NO3)3:

  • The above equation describes the reaction process between Nitric acid (HNO3) and Iron(III) hydroxide (Fe(OH)3).

  • The result of the reaction is the formation of Nitrogen dioxide (NO2), water (H2O) and Iron(III) nitrate (Fe(NO3)3).

  1. Reaction conditions:
  • The reaction occurs in excess acid environment.
  1. Reaction process:

  • During the reaction process, Nitric acid (HNO3) reacts with Iron(III) hydroxide (Fe(OH)3), creating Nitrogen dioxide (NO2), water (H2O) and Iron(III) nitrate (Fe(NO3)3).

  • The reaction occurs at a mol ratio of 4:1:2:2:1.

  1. Phenomena occurring:

  • When Nitric acid (HNO3) reacts with Iron(III) hydroxide (Fe(OH)3), brown Nitrogen dioxide (NO2) gas appears, simultaneously producing Iron(III) nitrate (Fe(NO3)3) compound and water (H2O).

  • Phenomenon: Brown Nitrogen dioxide (NO2) gas is released, the solution changes from the brown-yellow color of Iron(III) hydroxide (Fe(OH)3) to the light yellow color of Iron(III) nitrate (Fe(NO3)3).
