Denitrification is an important biologically-mediated process by which nitrate is reduced. This is especially important in environments with excess inputs of nutrients. Denitrification is shown in the following (unbalanced) equation: CH2O + NO3- + H+àH2O + N2 + CO2. What are the oxidation states of each element in the equation? Write the number under the element in the equation. Write the half reactions. Label which half reaction shows oxidation and reduction. Balance each half reaction. Write is the full balanced equation. Calculate the reduction potential DEo’. Calculate the Gibbs free energy DGo’. Will this reaction produce energy for bacterial growth?
