How can sulphide ions be distinguished from sulphite ions? – InterviewSolution

1.	How can sulphide ions be distinguished from sulphite ions?
Answer» SOLUTION :`AgNO_(3)` forms white ppt. with SULPHITE IONS while a black precipitate is obtained with sulphide ions. `BaCl_(2)` gives white ppt. with sulphite ions while no ppt. is obtained with sulphide ions. `FeCl_(3)` solution gives a red colouration with sulphite ions and a black ppt. is formed with sulphide ions.
