Question

When Cl, gas is passed through hot NaOH solution, oxidation number of C changes from
​

Answer 1

Answer:

The reaction of chlorine gas with hot and concentrated sodium hydroxide solution is

3Cl

2

+6NaOH⟶NaClO

3

+5NaCl+3H

2

O

Oxidation number of Cl is 0 in Cl

2

, −1 in NaCl and +5 in NaClO

3

So the oxidation number of chlorine changes from Zero to -1 and Zero to +5
