A 2010 article in Science magazine described “Sewage Treatment with Anammox.” [B. Kartal, J. G. Kuenen, and M. C. M. van Loosdrecht, Science, Vol. 328, pp. 702-703, 2010.] The authors noted that “Fixed nitrogen such as ammonium and nitrate [ions] must be removed [from sewage] to avoid toxic algal blooms in the environment.” One approach to removing ammonium ions is to use ammonium-oxidizing (anammox) bacteria. Two (unbalanced) reactions that are involved are:

NH4+(aq) + NO2(aq) → N2(g) + H2O()

NH4+(aq) + O2(g) → NO2(aq) + H2O()

Balance these two equations in acid solution.

Interpretation Introduction


The balanced equation for the given reactions should be written.

Concept introduction:

  • For chemical reaction balanced chemical reaction equation written in accordance with the Law of conservation of mass.
  • Net ionic equation only shows the net reaction that occurred after the completion of that particular reaction and. It does not indicate all the reactions that have happened in the corresponding system.
  • Law of conservation of mass states that for a reaction total mass of the reactant and product must be equal.
  • Stoichiometric factor is a relationship between reactant and product which is obtained from the balanced chemical equation for a particular reaction.


The unbalanced equations for the reactions are,


Balanced equation for the above reaction can be written as,
