Chemical reaction and equation As a result of the reaction, trivalent chromium oxide, pure nitrogen, is formed and water is released. The chemical equation for the reaction is as follows:
2 CrO3 + 2 NH3 = Cr2O3 + N2 + 3 H2O
We compose the equation of electronic balance.
Cr 6+ + 3e = Cr 3+ -oxidant, reduced.
N 3 – – 3e = N 0 – reducing agent, is oxidized.
