Nitrate (NO3) ions are obtained by the process of __________?

Correct answer: A. Nitrification

  • A. Nitrification
  • B. Fermentation
  • C. Denitrification
  • D. None of these

Explanation

Nitrification is the bacterial oxidation of ammonia or ammonium compounds first to nitrite and then to nitrate, NO3−. Fermentation produces organic products, while denitrification converts nitrate into nitrogen gas. Students may choose denitrification by remembering nitrate, but that process removes nitrate rather than forming it.

About Redox Reactions

Redox reactions involve oxidation and reduction occurring together, with electrons transferred between species or oxidation numbers changing. The topic covers assigning oxidation states, identifying oxidizing and reducing agents, balancing redox equations by oxidation number or half-reaction methods, and connecting chemical changes with galvanic and electrolytic cells.
