Potassium chromate solution is added to ...

Potassium chromate solution is added to aqueous solutions of metal nitrate. The yellow precipitate thus obtained are insoluble in acetic acid. Thse are subjected to flame, test, flame colour of individual ppt. is/are:

A

lilac

B

apple green

C

crimson red

D

brick red

Text Solution

Verified by Experts

The correct Answer is:
B
`Ba^(2+)` salts gives yellow precipitate with `K_(2)CrO_(4)` solution and this precipitate is not soluble in `CH_(3)CO OH`.
`Ba^(2+)` ions gives apple green colour in the flame test.
