A metal salt solution forms a yellow precipitate with potassium chromate in acetic acid, a white precipitate with dilute sulphuric acid, but gives no precipitate with sodium chloride or iodide, it is :
Text Solution
Verified by ExpertsThe correct answer is:
C
Ba 2+ + CrO 42– — → BaCrO 4 ↓ (yelllow) ; Ba 2+ + SO 4 — → BaSO 4 (white).
Ba 2+ + 2Cl – — → BaCl 2 (soluble in water).
K sp of SrCrO 4 is high in acetic acid, so no precipitate is formed.
Lead carbonate and basic lead carbonate both gives precipitate with K 2 CrO 4 and NaCl.
