Chromyl chloride vapours are dissolved in water and acetic acid and barium acetate solution is added, then :

A

the solution will remain colourless.

B

the solution will become dark green.

C

a yellow solution will be obtained.

D

a yellow precipitate will be obtained.

Text Solution

Verified by Experts

The correct Answer is:
D
`CrO_(2)Cl_(2)+2H_(2)O to H_(2)CrO_(4)+2HCl`
`H_(2)CrO_(4) +(CH_(3)CO O)_(2)Ba to BaCrO_(4) darr ("Yellow")+2CH_(3)CO OH`
