A

`Br_2 , KBrO_3`

B

`Cl_2 , KClO_3`

C

`I_2 , NaIO_3`

D

`Cl_2 , NaClO_3`

Text Solution

Verified by Experts

The correct Answer is:
B
`3Cl_2(g) +6KOH(aq) overset(Delta)toKClO_3 + 5KCl + 3 H_2O`
`Cl_2` is greenish yellow gas.
`KClO_3` is used in, fire works and safety matches as an oxidising agent.
