Laboratory Preparation
Chemistry of Alchemist (Science Diary)✒ Laboratory Preparation of Nitrogen using Sodium nitrite (NaNO 2 ) and Ammonium Chloride (NH 4 Cl). (The best example to Displacement Reactions). About Element Nitrogen (symbol N): Atomic number: 7, D iscovered and Isolated by Daniel Rutherford in 1772. Step I. NaNO 2 +NH 4 Cl ----convert to--- NH 4 NO 2 +NaCl (Reactants) ----Convert to--- (Products) Step II. NH 4 NO 2 ----convert to--- N 2 + 2H 2 O (Reactants)----Convert to--- (Products) # (Decomposition of Ammonium nitrite (NH 4 NO 4 ), produced gaseous Nitrogen (N 2 ) in Step II).
