Chromyl chloride vapours are dissolved in water and acetic acid and barium acetate solution is added, then:
Options
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.
Solution
CrO2Cl2 + 2H2O → H2CrO4 + 2HCl
H2CrO4 + (CH3COO)2Ba → BaCrO4↓ (Yellow) + 2CH3COOH
H2CrO4 + (CH3COO)2Ba → BaCrO4↓ (Yellow) + 2CH3COOH
