A greenish yellow gas reacts with an alkali metal hydroxide to form a halite which can be used in firworks and safety matches. The gas and halides respectively are -

A

`Br_(2),KBrO_(3)`

B

`CI_(2),KCIO_(3)`

C

`I_(2),NaIO_(3)`

D

`I_(2),KIO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
The halte used in fireworks and safety matches in `KCIO_(3)`. Thus the gas is `CI_(2)`
`3CI_(2)+6KOH rarr KCIO_(3)+5KCI+3H_(2)O`
