Question

If chlorine gas is passed through 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 `+3`

Answer 1

Correct Answer - A::C
When chlorine gas is passed through hot `NaOH` solution it produces `NaCl` and `NaClO_(3)`.

Oxidation state varies from 0 to - 1 and 0 to +5.
Hence, (a) and ( c) are correct choices.
