If chlorine gas is passed through a hot NaOH solution, two changes are observed in the oxidation number of chlorine during the reaction. These are ......... and  .............

a. 0 to +5

b. 0 to +3

c. 0 to -1

d. 0 to +1

Choose the correct option

1. (a, b)
2. (b, c)
3. (c, d)
4. (a, c)


Hint: The products obtained are NaCl, and NaClO3

When chlorine gas is passed through hot NaOH solution it produces NaCl and NaClO3
Oxidation state varies from 0 to - 1 and 0 to +5.
Hence, (a) and (c) are correct choices.
