What is N2H14? Important Knowledge about N2H14

  1. Definition of N2H14: N2H14 is commonly called “Hydrazine”. The English name of this substance is also Hydrazine. It consists of two Nitrogen atoms and four Hydrogen atoms. Each Nitrogen atom is bonded to two Hydrogen atoms by covalent bonds. The molecular weight of N2H14 is 32u. This substance does not form ions.

  2. Properties of N2H14:
    2.1 Physical properties: Hydrazine is in a liquid state, colorless, with a distinctive smell. Its pH varies depending on the concentration.
    2.2 Chemical properties: Hydrazine is highly flammable, reacting with oxygen in the air to form water and nitrogen.

  3. Common chemical equation: Hydrazine can react with metals, acids and non-metals but does not react with salts. For example, N2H14 + 4O2 -> 4H2O + 2N2.

  4. Preparation of N2H14:
    4.1 Lab synthesis: Hydrazine can be synthesized from ammonia and an oxidizing agent.
    4.2 Industrial synthesis: In industry, hydrazine is produced by reacting ammonia with sodium hypochlorite in an alkaline environment, then reduced with activated charcoal.
