About this document
Laboratory Nitrogen Preparation Method by Asmit is a document available to read on EtoBox.
This document describes the laboratory preparation of nitrogen gas from ammonium chloride and sodium nitrite. The reactants are mixed in a 1:1 molar ratio in a sealed test tube and heated to produce nitrogen gas. The gas is collected by displacement of water and may contain impurities that are removed by passing the gas through heated copper or dilute sulfuric acid. Precautions are taken to control the rate of the reaction and prevent explosion.
