What happens when 1. Cl2 reacts with hot concentrated solution of NaOH.

Question

What happens when

1. Cl₂ reacts with hot concentrated solution of NaOH.
2. XeF₆ is mixed with SbF₅ and heated.

Answer 1

1. Disproportionation reaction takes place in which chlorine from its zero oxidation state in Cl2 gets disproportionate into NaC103 (oxidised form) and NaCl (reduced form). The reaction is
   3Cl₂ + 6 NaOH (Hot and cone.) → NaClO₃ + 5 NaCl + 3 H₂O
2. XeF₆ + SbF₅ → [XeF₅]⁺[SbF₆]^–
   XeF₆ loses its F^– ion which is taken by SbF₅ to form cationic and anionic species. Due to ionic species, this mixture will conduct electricity in molten state.
