Identity correct statement: Elemental Na is easily oxidizing, Element sodium can be prepared and isolated by electrolyzing an aqueous solution of NaCl, Element Na is strong oxidizing agent, Elemental Na is insoluble in NH3
  1. Elemental Na is easily oxidizing
  2. Element sodium can be prepared and isolated by electrolyzing an aqueous solution of NaCl
  3. Element Na is strong oxidizing agent
  4. Elemental Na is insoluble in NH3
Explanation

Elemental sodium can lose electrons very easily so it acts as strong reducing agent. Na(s) → Na+ + e−

It dissolves in liquid ammonia giving out a conducting and reducing solution. 

It cannot be prepared by electrolysing sodium chloride solution in water as sodium reacts violently with water.
