An aqueous solution of a white salt A gives a white precipitate B on treatment with dilute HCl in cold condition. B is soluble in boiling water. An aqeous 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 diolute H_(2)SO_(4), boiled to remove CO_(2) and treated with a freshly prepared solution of FeSO_(4). concentratd H_(2)SO_(4) is added to the resulting solution. a brownn ring is formed at the junction of the two layers. Q. A solution of A, when treated with NH_(3), gives:

Q. A solution of A, when treated with NH_(3), gives:
Answer» a white precipitate SOLUBLE in an axcess of `NH_(3)` a whiite precipitate INSOLUBLE in an EXCESS of `NH_(3)` a grey precipitate solugble in an excess of `NH_(3)` a grey precipitate insoluble in an excess of `NH_(3)` Answer :B
