SO(2) and CO(2) both turn lime water (X)...

`SO_(2)` and `CO_(2)` both turn lime water `(X)` milky, `SO_(2)` also turns `K_(2)Cr_(2)O_(7)//H^(+) (Y)` green while `O_(2)` is soluble in pyrogallol `(Z)` turning it black. These gases are to be detected in order by using these reagents. The order is:

A

`(X),(Y),(Z)`

B

`(Y),(X),(Z)`

C

`(X),(Z),(Y)`

D

The correct order cannot be predicted

Text Solution

Verified by Experts
