A teacherr gave a student two salts (A) and (B) told him to identiify these salts. The student heated salt (A) strongly and observed two oxides to sulphur. He added NaOH solution to aqueous solution of (A) and observed a green precipitate, which turned brown on exposure to air. When he tok salt (B) to flame test, green colour was observed. On heating salt (B) with a solid compound (X) and concentrated sulphuric acid, orange red vapours are evolved. when this gas is passed through an aqueous solution of a base, the solution turns yellow. Q. Salt (B) suggest that the cation and anion in it are respectively: |
