An aqueous solution of a white salt A gives a white precipitate B on treatment with dilute HCI in cold conditions. B is soluble in boiling water. An aqueous solution of A gives a yellow precipitate on treatment with a solution of `K_(2)CrO_(4)`. The soda extract of A is acidified with dilute `H_(2)SO_(4)` boiled to remove `CO_(2)` and treated with a freshly prepared solution of `FeSO_(4)` Concentrated `H_(2)SO_(4)` is added to the resulting solution (along the walls of the test tube so that the `H_(2)SO_(4)` forms a separate layer). A brown ring is formed at the junction of the two layers.
On treatment with a Kl solution, an aqueous solution of A will give

Options

A. a yellow precipitate soluble in boiling water
B. a yellow precipitate insoluble in boiling water
C. a white precipitate soluble in boiling water
D. a white precipitate insoluble in boiling water

Answer

A

Explanation

Yellow precipitate due `PbI_(2)`
