Question
A mixture of two colourless substances was dissolved in water. When gaseous Cl2 was passed through the solution, containing small quantity of CCl4 a violet colour developed in organic layer. Addition of BaCl2 to the original solution give a white precipitate. The mixture contains :
Options
A.salts of nitrate and chloride.
B.salts of bromide and chloride.
C.salts of iodide and sulphate.
D.salts of sulphate and chloride.
Solution
2I- + Cl2 → I2 + 2Cl-. I2 being covalent dissolves in chloroform giving purple or violet solution.
Ba2+ + SO42- → BaSO4 ↓ (white).
Ba2+ + SO42- → BaSO4 ↓ (white).
