A metal salt solution forms a yellow precipitate with potassium chromate in acetic acid, a white precipitate with dilute `H_2 SO_4` but gives no precipitate with sodium chloride or iodide, it is

A

lead carbonate

B

basic lead carbonate

C

barium carbonate

D

strontium carbonate

Text Solution

Verified by Experts

The correct Answer is:
C
`Ba^(2+)+CrO_(4)^(2-)toBaCrO_(4)darr("yellow"),Ba^(2+)+SO_(4)toBaSO_(4)`(white).
`Ba^(2+)+2Cl^(-)toBaCl_(2)`(soluble in water)
`K_(sp)` of `SrCrO_(4)` is high in acetic acid, so no precipitate is fomed.
Lead carbonate and basic lead carbonate both gives precipitate with `K_(2)CrO_(4)` and `NaCl`
