Hot and concentrated sodium hydroxide reacts with chlorine to give:

  1. A.Sodium chloride and sodium hypochlorite
  2. B.Sodium chloride and sodium chlorateCorrect answer
  3. C.Sodium chloride and sodium chlorite
  4. D.Sodium chloride and sodium perchlorate

Solution

With hot and concentrated NaOH, chlorine undergoes disproportionation to form sodium chloride (NaClNaCl), sodium chlorate (NaClO3NaClO_3), and water: 3Cl2+6NaOH→5NaCl+NaClO3+3H2O3Cl_2 + 6NaOH \rightarrow 5NaCl + NaClO_3 + 3H_2O.
